Quake Hits Southern Iran

TEHRAN (FNA)- An earthquake measuring 5.3 on the Richter scale jolted the town of Ahal in Fars province, Southern Iran, on Thursday.

The Seismological center of Fars province affiliated to the Geophysics Institute of Tehran University registered the quake at 06:27 hours local time (0157 GMT).

The epicenter of the quake was located in an area 53.8 degrees in longitude and 26.9 degrees in latitude.

There are yet no reports on the number of possible casualties or damage to properties by the quake.

Iran sits astride several major faults in the earth’s crust, and is prone to frequent earthquakes, many of which have been devastating.

The worst in recent times hit Bam in southeastern Kerman province in December 2003, killing 31,000 people – about a quarter of its population – and destroying the city’s ancient mud-built citadel.

The deadliest quake in the country was in June 1990 and measured 7.7 on the Richter scale. About 37,000 people were killed and more than 100,000 injured in the northwestern provinces of Gilan and Zanjan. It devastated 27 towns and about 1,870 villages.

Last month, two quakes in Northwestern Iran also claimed the lives of 306 people and injured more than 4500 others.

An earthquake measuring 6.2 on the Richter scale jolted Ahar in East Azerbaijan province at 16:00 hours local time (1130GMT) on August 11. The epicenter of the quake was located in an area 46.8 degrees in longitude and 38.4 degrees in latitude.

Almost an hour later another quake with magnitude 6 on the Richter scale jolted Varzaqan at 17:04 hours local time (1234GMT) in the same province. The epicenter of the quake was located in an area 46.7 degrees in longitude and 38.4 degrees in latitude.

Tectonic Summary

The September 5th 2012 M 7.6 earthquake beneath the Nicoya Peninsula, Costa Rica, occurred as the result of thrust faulting on or near the subduction zone interface between the Cocos and Caribbean plates. At the latitude of this earthquake, the Cocos plate moves north-northeast with respect to the Caribbean plate at a velocity of approximately 77 mm/yr, and subducts beneath Central America at the Middle America Trench.

Over the past 40 years, the region within 250 km of the September 5th earthquake has experienced approximately 30 earthquakes with M 6 or greater; two of these were larger than M 7, and neither caused documented fatalities. The first was a M 7.2 in August of 1978, 9 km to the north-northeast of the September 5th 2012 event; the second had a magnitude of M 7.3, and struck a region just over 50 km to the east-southeast in March 1990. The earthquake of October 5, 1950, M 7.8, occurred in the general area of the September 5th 2012 earthquake, although the hypocenter of the earlier earthquake is not known to high precision. The 1950 earthquake caused damage in northwestern Costa Rica and in the Valle Central of Costa Rica, but no reported casualties. The closest earthquake to cause fatalities in recent history was the M 6.5 April 1973 earthquake approximately 80 km to the northeast, which resulted in 26 fatalities and over 100 injuries.

Seismotectonics of the Caribbean Region and Vicinity

Extensive diversity and complexity of tectonic regimes characterizes the perimeter of the Caribbean plate, involving no fewer than four major plates (North America, South America, Nazca, and Cocos). Inclined zones of deep earthquakes (Wadati-Benioff zones), ocean trenches, and arcs of volcanoes clearly indicate subduction of oceanic lithosphere along the Central American and Atlantic Ocean margins of the Caribbean plate, while crustal seismicity in Guatemala, northern Venezuela, and the Cayman Ridge and Cayman Trench indicate transform fault and pull-apart basin tectonics.

Along the northern margin of the Caribbean plate, the North America plate moves westwards with respect to the Caribbean plate at a velocity of approximately 20 mm/yr. Motion is accommodated along several major transform faults that extend eastward from Isla de Roatan to Haiti, including the Swan Island Fault and the Oriente Fault. These faults represent the southern and northern boundaries of the Cayman Trench. Further east, from the Dominican Republic to the Island of Barbuda, relative motion between the North America plate and the Caribbean plate becomes increasingly complex and is partially accommodated by nearly arc-parallel subduction of the North America plate beneath the Caribbean plate. This results in the formation of the deep Puerto Rico Trench and a zone of intermediate focus earthquakes (70-300 km depth) within the subducted slab. Although the Puerto Rico subduction zone is thought to be capable of generating a megathrust earthquake, there have been no such events in the past century. The last probable interplate (thrust fault) event here occurred on May 2, 1787 and was widely felt throughout the island with documented destruction across the entire northern coast, including Arecibo and San Juan. Since 1900, the two largest earthquakes to occur in this region were the August 4, 1946 M8.0 Samana earthquake in northeastern Hispaniola and the July 29, 1943 M7.6 Mona Passage earthquake, both of which were shallow thrust fault earthquakes. A significant portion of the motion between the North America plate and the Caribbean plate in this region is accommodated by a series of left-lateral strike-slip faults that bisect the island of Hispaniola, notably the Septentrional Fault in the north and the Enriquillo-Plantain Garden Fault in the south. Activity adjacent to the Enriquillo-Plantain Garden Fault system is best documented by the devastating January 12, 2010 M7.0 Haiti strike-slip earthquake, its associated aftershocks and a comparable earthquake in 1770.

Moving east and south, the plate boundary curves around Puerto Rico and the northern Lesser Antilles where the plate motion vector of the Caribbean plate relative to the North and South America plates is less oblique, resulting in active island-arc tectonics. Here, the North and South America plates subduct towards the west beneath the Caribbean plate along the Lesser Antilles Trench at rates of approximately 20 mm/yr. As a result of this subduction, there exists both intermediate focus earthquakes within the subducted plates and a chain of active volcanoes along the island arc. Although the Lesser Antilles is considered one of the most seismically active regions in the Caribbean, few of these events have been greater than M7.0 over the past century. The island of Guadeloupe was the site of one of the largest megathrust earthquakes to occur in this region on February 8, 1843, with a suggested magnitude greater than 8.0. The largest recent intermediate-depth earthquake to occur along the Lesser Antilles arc was the November 29, 2007 M7.4 Martinique earthquake northwest of Fort-De-France.

The southern Caribbean plate boundary with the South America plate strikes east-west across Trinidad and western Venezuela at a relative rate of approximately 20 mm/yr. This boundary is characterized by major transform faults, including the Central Range Fault and the Bocon?-San Sebastian-El Pilar Faults, and shallow seismicity. Since 1900, the largest earthquakes to occur in this region were the October 29, 1900 M7.7 Caracas earthquake, and the July 29, 1967 M6.5 earthquake near this same region. Further to the west, a broad zone of compressive deformation trends southwestward across western Venezuela and central Columbia. The plate boundary is not well defined across northwestern South America, but deformation transitions from being dominated by Caribbean/South America convergence in the east to Nazca/South America convergence in the west. The transition zone between subduction on the eastern and western margins of the Caribbean plate is characterized by diffuse seismicity involving low- to intermediate-magnitude (M<6.0) earthquakes of shallow to intermediate depth.

The plate boundary offshore of Colombia is also characterized by convergence, where the Nazca plate subducts beneath South America towards the east at a rate of approximately 65 mm/yr. The January 31, 1906 M8.5 earthquake occurred on the shallowly dipping megathrust interface of this plate boundary segment. Along the western coast of Central America, the Cocos plate subducts towards the east beneath the Caribbean plate at the Middle America Trench. Convergence rates vary between 72-81 mm/yr, decreasing towards the north. This subduction results in relatively high rates of seismicity and a chain of numerous active volcanoes; intermediate-focus earthquakes occur within the subducted Cocos plate to depths of nearly 300 km. Since 1900, there have been many moderately sized intermediate-depth earthquakes in this region, including the September 7, 1915 M7.4 El Salvador and the October 5, 1950 M7.8 Costa Rica events.

The boundary between the Cocos and Nazca plates is characterized by a series of north-south trending transform faults and east-west trending spreading centers. The largest and most seismically active of these transform boundaries is the Panama Fracture Zone. The Panama Fracture Zone terminates in the south at the Galapagos rift zone and in the north at the Middle America trench, where it forms part of the Cocos-Nazca-Caribbean triple junction. Earthquakes along the Panama Fracture Zone are generally shallow, low- to intermediate in magnitude (M<7.2) and are characteristically right-lateral strike-slip faulting earthquakes. Since 1900, the largest earthquake to occur along the Panama Fracture Zone was the July 26, 1962 M7.2 earthquake.

Description
A preliminary review revealed some structural damage near the epicenter, but no reports of deaths or injuries, said Douglas Salgado, a geographer with Costa Rica’s National Commission of Risk Prevention and Emergency Attention. He said a tsunami alert had been called off for Costa Rica. The review also uncovered a landslide on the main highway that connects the capital of San Jose to the Pacific coast city of Puntarenas, Salgado said. Hotels and other structures suffered cracks in walls and saw items knocked off shelves. “There’s chaos in San Jose because it was a strong earthquake of long duration,” Salgado said. “It was pretty strong and caused collective chaos.” Michelle Landwer, owner of the Belvedere Hotel in Samara, north of the epicenter, said she was having breakfast with about 10 people when the earthquake struck. “The whole building was moving, I couldn’t even walk,” Landwer said. “Here in my building there was no real damage. Everything was falling, like glasses and everything.” At the Hotel Punta Islita in the Guanacaste area, “everybody is crying a lot and the telephone lines are saturated,” said worker Diana Salas, speaking by telephone, but she said was no damage there. In the coastal town of Nosara, roughly 50 miles (80 kilometers) north of the epicenter, trees shook violently and light posts swayed. Teachers chased primary school students outside as the quake hit. Roads cracked and power lines fell to the ground. A tsunami warning was in effect for Costa Rica, Panama and Nicaragua, the Pacific Tsunami Warning Center said in a bulletin. It said it was unknown if a tsunami was generated, but the warning was based on the size of the earthquake.

Description
Three people, two from heart attacks, when a major earthquake hit northwestern Costa Rica on Wednesday, authorities said. At least 20 people were injured and two others were missing, but the Red Cross said those numbers could rise as damage assessment teams reached more areas. Costa Rican President Laura Chinchilla, however, said there were no deaths caused by the earthquake, contradicting the Red Cross. The quake — initially rated at magnitude 7.9 but then revised by the the U.S. Geological Survey to 7.6 — struck at 10:42 a.m. ET at a depth of about 25 miles about 7 miles southeast of Nicoya. The town of 15,000 people is near the Pacific coast, about 90 miles from the capital, San Jose. Government buildings, including the National Assembly complex in San Jose, were under evacuation orders, the newspaper La Nacion reported. Thousands of youngsters were sent home from school as a precaution against aftershocks. The Pacific Tsunami Warning Center canceled tsunami warnings for Costa Rica, Panama and Nicaragua.A man died in Nicoya when a wall fell on him, said Vanessa Rosales, president of the National Emergency Commission. He wasn’t immediately identified. A second person, identified only as an elderly man named Smith, died of a heart attack in San Antonio in Desamparados province, authorities said. A woman from the Pacific coastal town of Carrillo also died from a heart attack during the quake, Eva Camargo, director of the hospital in Filadelfia, told the news service Terra. The woman was about 55 years old and had the surnames Rodriguez Machado. Camargo said the hospital was treating at least 20 people for quake-related injuries. Two other people suffered minor injuries at the Hotel Barceló Tambor Beach in Playa Tambor, said Alcides Gonzalez, mayor of the coastal town of Paquera. The nature of their injuries wasn’t immediately known, but Gonzalez told La Nacion that the resort hotel was damaged when a pipe collapsed. It couldn’t be immediately determined whether the victims were tourists or hotel employees. Costa Rican President Laura Chinchilla Miranda met with the National Emergency Council and the International Committee of the Red Cross later in the morning. In a news conference monitored by NBC News, Chinchilla confirmed that several buildings had been damaged in the capital and called on residents of the western coast to remain calm.Power was out in Puntarenas, capital of the province of the same name, where Monsignor Sanabria Hospital was evacuated for a structural review amid visible signs of damage. A bridge over the Sucio River collapsed in the town of Sarapiqui, local media reported. Some roads were blocked by landslides, and the Red Cross said rescue teams were unable to reach some areas.

Description
A powerful earthquake rocked Costa Rica on Wednesday, causing the deaths of at least two people, damaging buildings, and briefly triggering a tsunami warning. Unconfirmed media reports of people being treated for injuries. A spokesman for the local Red Cross said two people died during the earthquake, one from a heart attack. He was not immediately able to confirm media reports the other person had been crushed under a collapsing wall. The center had earlier warned of tsunamis for as far afield as Mexico and Peru. The quake’s epicenter was in western Costa Rica about 87 miles (140 km) from San Jose, the US Geological Survey (USGS) said, and it was felt as far away as Nicaragua and Panama. The Guanacaste region around the epicenter is known for its beaches, surf and volcanoes.

06.09.2012 Volcano Eruption Indonesia Sunda Strait, [Anak Krakatoa Volcano] Damage level Details

Volcano Eruption in Indonesia on Monday, 03 September, 2012 at 18:44 (06:44 PM) UTC.

Back

Updated: Thursday, 06 September, 2012 at 03:10 UTC
Description
Clouds of volcanic ash from Anak Krakatau, or child of Krakatau, have become so prominent in recent days that Indonesian authorities have issued a warning for local residents and tourists. “The ash was carried by wind from the southeast to the south, reaching Bandarlampung,” Nurhuda, head of the observation and information section of the Meteorology, Climatology and Geophysics Agency (BMKG) in Lampung province told state news agency Antara. The major population center of Bandarlampung is the capital of the Lampung province and is the same distance from the volcano as the Indonesian capital of Jakarta. “We also advise fishermen and tourists not to come within a radius of 3 kilometers of Anak Krakatau. The thick plumes of smoke sent off by Krakatau contain toxic material that is hazardous for your health,” said Andi Suhardi, head of the Anak Krakatau observation post in Hargo Pancuran village. Officials advised residents to wear masks when traveling outdoors to protect themselves against the ash. Short term effects of volcanic ash could include respiratory discomfort, including nose and throat irritation. Those with pre-existing respiratory conditions could be susceptible to more long term effects.In addition to having negative effects on the human population, volcanic ash has also been proven to be harmful to livestock. The ash has been observed causing cosmetic damage, such as abrasion of the teeth, as well as more dire impacts like fluorine poisoning from the heightened levels of hydrogen fluoride found in volcanic debris. Following the 1995 Mount Ruapehu eruptions in New Zealand, two thousand sheep died after being affected by fluorosis while grazing on land littered with the ash. The added weight of ash in the animals’ wool also led to widespread fatigue affecting the flocks. Observations of Anak Krakatau could be hinting toward a major eruption as the volcanology office in Bandung has recorded almost 90 eruptions per day over the past week. In addition, Nurhuda added that the volcano has been observed spewing red hot lava up almost 1000 feet above its peak in recent days. A major eruption of the tiny island volcano would be the first one for Indonesia since the eruption of Mount Merapi. In October 2010, the Indonesian government sounded the alarm regarding Mount Merapi and warned villagers in threatened areas to move to safe areas. The evacuation orders affected at least 19,000 people, but by the time volcanic activity had subsided, over 350,000 people were displaced.The eruptions would eventually claim the lives of 353 people with a number of victims succumbing to severe burns and some bodies being found on the volcano’s slopes. The mountain continued to erupt until November 2010 and on December 3rd the official alert status was reduced to level 3, from level 4, the highest possible level. After the eruptions at Mount Merapi subsided, officials declared them the worst the country had seen since the 1870s. In addition to death, damage and displacement, the volcanic activity also disrupted air travel, grounding flights from Indonesia and Australia for over a month.

Volcano Eruption in Guatemala on Wednesday, 05 September, 2012 at 02:58 (02:58 AM) UTC.

Description
The Fuego volcano in central Guatemala is continuing to erupt, shooting lava and columns of ash into the air, and causing concerns of a possible ash cloud that could halt flights in the area. The volcano overlooks the tourist city of Antigua and is one of central America’s most active volcanoes. Lava flows of around 1000m are being spewed out down the west and east sides of the volcano. No evacuations have been ordered, but aviation authorities have been alerted about a potential ash cloud, and air traffic is expected to be hindered.

Severe weather watch after ‘amazing’ storm in Christchurch, New Zealand

ONE News

Lightning display in Christchurch.

A severe weather watch is in place for Canterbury today, after Christchurch was hit by freakish weather last night leaving conservatories damaged and lifting a roof off a house.

Emergency services in Christchurch were kept on their toes when lightning, thunder, rain and hail the size of golf balls hit the region shortly after 6pm. It finished just after 7pm.

MetService said that the weather watch covers the possibility of northwesterlies gusting to severe gale strength at times in inland parts of Canterbury, Otago and Southland from late Wednesday through Thursday.

The Fire Service received about 20 callouts during and after the storm last night, about damage to roofs and conservatories from the hail, but many were false alarms triggered by the weather.

“Two conservatories collapsed because of the hail, and we had to assist one family whose roof had begun to lift,” a Fire Service spokesman told NZ Newswire.

The spectacular show could be seen and heard over most of the city, with MetService reporting more than 200 lightning flashes during the storm.

Joy Hartley-Anderson commented on the ONE News Facebook page that the storm “was awesome”.

“Just something special for us from mother nature to mark the two year anniversary of shaking the crap out of us.. :-),” she posted.

On September 4, 2010, a 7.1 magnitude earthquake shook the ground beneath Christchurch more strongly than it had for thousands of years.

Flo Brown posted that the weather display was “amazing” and a “very special light display”.

However, Tania Ake said it was “pretty bad at Redwood” and freaked her out.

The storm caused a power outage in the Southbridge, but electricity company Orion managed to restore power to all but four customers.

The last time Canterbury had a hail storm of this size, there were a huge number of insurance claims for hail damage on vehicles.

Meanwhile, MetService said strong westerlies should remain over central New Zealand this morning.

The forecaster said westerlies could become severe gale strength at times in central Hawkes Bay and northern Wairarapa this morning.

 

Today Extreme Weather USA State of Kentucky, [Louisville and Jeffersonville] Damage level Details

Extreme Weather in USA on Thursday, 06 September, 2012 at 03:23 (03:23 AM) UTC.

Description
A severe thunderstorm rumbled through the region Wednesday afternoon, knocking out power for more than 6,000 people in Jefferson County and causing temporary flooding of some Louisville streets. Lightning strikes from the storm caused two house fires in Jefferson County, said Jody Johnson Duncan, a spokeswoman for MetroSafe Communications. The fires, at 2201 Deveron Drive in Shively and 7007 Windham Parkway in Prospect, were reported between 3:30 and 4:30 p.m. No injuries were reported from the fires. The storm also caused several blown electrical transformers and knocked down wires around the city, Johnson Duncan said. Two people had to be rescued from their vehicles after driving into high water at South 7th Street and Berry Boulevard. The Jefferson County Public Schools delayed releasing elementary students while the storm passed through, said Rick Caple, the transportation director. The weather service issued a severe thunderstorm warning for the storm, which it said was capable of producing damaging winds of more than 60 mph. The Metropolitan Sewer District, which tracks rainfall closely at several monitors, said that the storm produced 1.25 inches of rain in about 30 minutes, with some areas getting up to a half inch in as little as five minutes. Water pressure from the storm blew the covers off about 10 manholes, but all MSD storm water and sewer facilities were operating after the storm, said MSD spokesman Steve Tedder. He said a few pumping stations used backup power. Several trees were reported down in Jeffersonville, the weather service said. A weather spotter also reported a large tree down on a railroad track in Anchorage and another person reported on Facebook that a small car was crushed at Woodbourne Avenue. More than 6,000 electric customers in Jefferson County were without service at 6 p.m., according to Louisville Gas & Electric. The outages were spread across the county, with the outages tracking the path of the storm. The weather service also issued a tornado warning for northeastern Shelby County that was in effect until 5:05 p.m. There were no immediate reports of tornadoes.
Today Extreme Weather USA State of Alaska, Anchorage Damage level Details

Extreme Weather in USA on Thursday, 06 September, 2012 at 03:11 (03:11 AM) UTC.

Description
An overnight wind storm with gusts of over 100 miles an hour at high elevations knocked out power to at least half of Alaska’s largest city in the biggest outage in Anchorage’s center in decades, municipal and utility officials said on Wednesday. “It’s incredibly substantial. A huge proportion of Anchorage is affected,” said Dawn Brantley, emergency program manager for the Municipality of Anchorage. She said she did not know yet what percentage of the city overall had been affected but called the outage the biggest for downtown Anchorage in decades. Electricity was cut to at least half of Anchorage, including nearly all customers of the utility that serves the central part of the city, the officials said. Tens of thousands of homes and businesses remained without power by midday on Wednesday, Brantley said. Both of Anchorage’s electrical utilities, city-owned Municipal Light and Power and member-owned Chugach Electric Association, suffered outages. Power outages caused schools, local colleges and state offices to close on Wednesday. Access to Joint Base Elemendorf-Richardson was limited to essential workers. But municipal offices were open, Brantley said. The storm knocked down large trees and caused some property damage, but no storm-related injuries were reported, she said.

Portugal gets foreign help battling wildfires amid hot weather, wind and drought

(Francisco Seco/ Associated Press ) – A firefighter steps back while working to douse a fire in Alvaiazere, center Portugal, Tuesday, Sept. 4, 2012. A Portuguese official says authorities have asked other European countries to send help as the country’s firefighters struggle to contain forest blazes being fueled by high temperatures and strong winds. More than 1,700 firefighters, almost 500 vehicles and 13 aircraft fought blazes mostly in the north of the country.

By Associated Press, Published: September 4

LISBON, Portugal — Water-dumping aircraft from Spain and France on Tuesday joined Portugal’s battle to halt the spread of wildfires through thick woodland in the country’s north left tinder-dry by months of drought.Spain and France sent two aircraft each, Portugal’s Civil Protection Service said, a day after authorities appealed for help for fire crews struggling to contain blazes amid high temperatures and strong winds.
At mid-afternoon Tuesday, the Civil Protection Service said just over 1,000 firefighters were tackling 10 blazes in steep hills and dense forests in northern Portugal.More than 350 vehicles and 19 aircraft, including those from Spain and France, were on duty, it said on its website.Interior Minister Miguel Macedo met with national fire officials at their command center just outside Lisbon and said the temperatures above 30 degrees Celsius (86 Fahrenheit), high winds and difficult terrain “have produced what firefighters call a perfect storm.”He said the difficult conditions were forecast to continue another 48 hours.Portugal is in the grip of one of its worst droughts in recent memory. At the end of July, 58 percent of Portugal was enduring extreme drought conditions and 26 percent was in severe drought, the two highest classifications, according to the Meteorological Institute.The lack of rain has left forests vulnerable. Between January and July, fires scorched some 67,000 hectares (165,550 acres) of forest and scrubland — triple the amount recorded in the same period last year, the National Forest Authority said in its latest report.The Civil Protection Service said firefighters extinguished two major forest blazes that had burned for more than 30 hours from Sunday and claimed the life of one person.In remote villages, locals used buckets and garden hoses to douse flames encroaching on their homes as black smoke billowed across blue skies.Despite the difficulties, Tuesday was quieter than the previous day when more than 7,300 firefighters and almost 2,000 vehicles attended 289 major forest blazes.The largest outbreak was in Ourem, near Leiria, where a blaze that started midday Sunday killed a 54-year-old farmer trying to protect his property. That fire was brought under control early Tuesday.

Leslie upgraded to a hurricane, on path towards Bermuda


Hurricane Leslie (NOAA) Tropical storm Leslie added 5 mph to its peak wind speed (up to 75 mph), becoming the 6th hurricane in the Atlantic in the 2012 season. It’s positioned 465 miles south-southeast of Bermuda and slowly headed in that direction. It may be in the island’s vicinity Saturday or Sunday.

Link: Hurricane Tracker

The 6 hurricanes so far in 2012 matches the average number in an entire season slightly less than half way through. NOAA’s updated hurricane forecast called for 5-8 hurricanes, 2 to 3 of which would be major (category 3 or higher). So far, there have been no major hurricanes.

While forecasting hurricane intensity is highly uncertain, Leslie has the potential to strengthen into a major hurricane. By Saturday, the National Hurricane Center predicts its peak winds will be 110 mph – which is right at the major hurricane threshold (category 3 storms have maximum winds of at least 111 mph).

We’ll have more on Leslie and the rest of the tropics tomorrow.

Tropics: Leslie and Michael strengthen, while Isaac may come back for an encore

By Brian McNoldy

The extremely active 2012 Atlantic hurricane season continues. Leslie and Michael are swirling in the open sea, while a piece of Isaac’s remnants might regenerate into tropical storm Nadine.


Model forecasts for tropical storm Leslie steer it towards Bermuda Saturday into SundayBermuda, Nova Scotia and Newfoundland need to be on-guard for possible impacts from Leslie. The northern Gulf Coast should keep an eye on the ghost of Isaac.

Leslie

In the past six days, Leslie has been in a moderate-to-high shear environment, limiting its intensity, but not dismantling it. Now, models are in fairly good agreement that the shear should subside and the storm will finally become a hurricane.

While the track remains far off the U.S. East Coast, Leslie could impact Bermuda later this weekend, and likely as a rather strong hurricane.

The latest suite of model runs keeps a tight cluster centered on the tiny island. At 11 a.m. this morning, Leslie’s maximum sustained winds were 70 mph; it was centered about 470 miles south-southeast of Bermuda and drifting north at 2mph. In the longer term, Nova Scotia and Newfoundland need to be on the lookout.

Michael


Michael formed on Monday afternoon as a depression, but was quickly upgraded to the 13th named storm of the season on Tuesday morning.

It’s a very small system, with tropical storm force winds extending just 35 miles from the center (recall Isaac’s typically extended about 200 miles from the center). It is very far from any land, but the best reference point would be the Azores islands, 1155 miles to the northeast.

Michael is a 50 mph tropical storm and is not forecast to change much in the coming days… perhaps gradually strengthening as it meanders generally northward.

Isaac/Nadine

Finally, in an unusual fashion, the remnants of Isaac may be making a comeback… over the northern Gulf coast!

Tracing the low-level circulation (850mb vorticity – area of spin about 5,000 feet aloft) over the past week reveals a complex history of what was once Hurricane Isaac. After moving inland across Louisiana, Arkansas, and Missouri, the circulation was distorted and ripped apart by a trough.


I simplified the events that transpired in the crude diagram shown here (to the right). Sometime around Monday, it appears that a part of the circulation split off to the northeast and a part split off to the south. This was not a clean separation, and someone else might analyze the circulation tracks slightly differently. But the basic point is that there is a disturbance re-entering the northern Gulf of Mexico that has some of Isaac in its “genes”. However, should this disturbance become a tropical storm, it would get a new name – Nadine – because there is not enough of Isaac’s circulation in its pedigree. As the National Hurricane Center described on its Facebook page:

There have been quite a few inquiries about whether the name “Isaac” would be given to the area of disturbed weather currently located along the northern coast of the Gulf of Mexico, if it were to develop into a tropical cyclone. The short answer is no, it would get a new name.


As of this morning, the disturbance is certainly active and producing heavy rain (regional radar loop) across parts of LA, MS, AL, and FL, but the bulk of the thunderstorm activity is offshore. For the most part, model guidance suggests that it will continue to drift toward the Gulf, then get nudged back east toward northern Florida… making “landfall” this weekend. Even if it doesn’t get named or develop beyond what it is now, it should still be a big rain maker for the northeast Gulf coast over the next few days.

Seasonal update

As an update to my post on Friday regarding seasonal activity and Accumulated Cyclone Energy (ACE), as of 8 a.m. this morning, ACE stands at 66.3, compared to the average (1981-2010 base) 39.7 by the beginning of September 5 —- a whopping 167% of average for this date.

We’re also already on the 13th named storm as of September 4th, which isn’t a record, but it’s really close. The only years to beat that date are 2005 and 2011 when the 13th named storm formed on September 2nd. Since records began 160 years ago, only about 8% of years even reach the 13th named storm by the END of the season, let alone prior to the peak.

But, in terms of major hurricanes (Category 3+), this season is definitely lagging behind its peers. By this date in 2005, we already had three major hurricanes (Dennis, Emily, and Katrina), and by this date in 2011, we had one major hurricane (Katia). This year, we have had none.

Swamp Rats & Baby Dolphins! How Hurricanes Impact Animals

Clean-up crews are removing the rotting nutria carcasses with pitchforks and front-end loaders. The smell is reportedly terrible.

The aftermath of Hurricane Isaac has washed ashore tens of thousands of dead “swamp rats,” invasive species whose rotting corpses are now presenting a health hazard in Mississippi.

The drowned rodents, known as nutria, are a stark reminder of the effects of hurricanes on wildlife, which can range from mass death to – surprisingly enough – dolphin baby booms. In the case of the nutria, the drownings may be a blessing for the Gulf Coast, where the beaver-like creatures wreck havoc on native marsh vegetation.

The clean-up, though, is proving unpleasant.

“They’re actually starting to swell up and bust,” Hancock County Supervisor David Yarborough told local news station WLOX. “It smells really bad.”

Animals and hurricanes

Nutria aren’t the only animals to suffer after hurricanes. A study of alligators in southwest Louisiana after Hurricane Rita hit in 2005 found that the reptiles were physically stressed a month after the initial storm surge inundated their marshy habitat. Blood tests on the gators showed elevated stress hormones as well as other signs of ill health, the researchers reported in February 2010 in the Journal of Experimental Zoology Part A: Ecological Genetics and Physiology.

Research on Florida manatees has suggested that docile “sea cows” die more frequently during years with extreme storms, perhaps due to immediate causes like getting swept out to sea, or perhaps due to post-hurricane environmental changes such as cooling in coastal waters, according to a 2006 paper published in the journal Estuaries and Coasts. That study tracked a handful of manatees through the 2004 and 2005 hurricane seasons and found that the animals tended to “ride out” the storms in place rather than attempt to avoid them.

Other studies have found changes in fish populations right after hurricanes, as well as changes in phytoplankton, the algal basis of the ocean food chain, though these changes are short-lived. Sometimes, though, hurricane effects echo over long time periods. A 2010 study on bottlenose dolphins found that two years after Hurricane Katrina, the number of baby dolphins in the Gulf of Mexico suddenly skyrocketed.

Some of the jump could be explained by dolphin mamas getting pregnant sooner than usual after losing their previous calves in the storm, the researchers reported in the journal Marine Mammal Science. But the storm had another effect: It destroyed a significant chunk of the Gulf of Mexico fishing fleet. Fewer fishermen meant more food for dolphins and their young, the researchers concluded.

Nutria death zone

Mississippi’s nutria population took a hit from Isaac. Sanitation workers have been cleaning up the carcasses with pitchforks and front-end loaders.

“Estimates are there will be over 20,000 carcasses, but that is unclear now,” Robbie Wilbur, a spokesman for the Mississippi Department of Environmental Quality, told LiveScience. “Eventually, the totals will be numerated in tons when they’re all disposed.”

The carcasses are being sent to the Pecan Grove landfill in Harrison County, Miss., Wilbur added.

“It’s starting to get bad,” said Mark Williams of the Department of Environmental Quality’s Solid Waste Management branch. “It’s heated up over the last two or three days, and of course that really expedites the degradation process.”

Nutria are native to South America, but the rodents were brought to North America in the late 1800s and farmed for their fur. Escaped and released nutria established themselves in the marshes of the Gulf Coast, where they gnaw the roots of marsh plants, destroying the vegetal web that keeps the marshes from washing away.

Hurricane Isaac likely won’t set Mississippi’s nutria population back for long. Nutria can produce litters with as many as 13 babies, and they’re capable of reproducing twice a year starting at as early as four months of age. Baby nutria begin supplementing their mother’s milk with marsh vegetation within hours of birth.

Wild storm dumps torrential rain, hail on Perth, South-West Australia – more coming

Thousands of homes were without power across Perth this afternoon in the aftermath of a cold front that lashed the city today.

A Western Power spokeswoman said thousands of homes had without power at different times during the day, but the number was steadily decreasing.

Midland, Upper Swan and Pickering Brook were the worst affected areas.

Many home owners are tonight counting the cost of damage caused by the storm.

Nine News reports that a lightning strike caused a fire at a house in Bellevue caused more than $100,000 in damage, while wild winds brought down trees, including one in Forrestfield that crushed a car.

Meanwhile, the Bureau of Meteorology warns that widespread damaging winds could tonight affect areas in a line south from Augusta to Lake Grace to Israelite Bay, including people in or near Bridgetown, Albany, Katanning and Esperance.

A deep low south of Bremer Bay will move eastwards during the evening, producing winds up to 100km/h which could result in damage to homes and property.

Dangerous gusts in excess of 125 km/h could cause significant damage or destruction to homes and property in localised areas.

Isolated thunderstorms and small hail is also possible.

The Bureau warned of dangerous surf conditions which could cause significant beach erosion.

Broad cold front sweeps over Western Australia

A cold front, which crossed the coast from Geraldton, 450km north of Perth, to Bremer Bay, 500km southeast, late yesterday brought widespread heavy rains and hail today.

There were numerous reports of small, but intense hailstorms across the metro area, including the city, Ellenbrook, Woodvale and Midland to the east.

One PerthNow commenter, from Midland, said a fierce hailstorm had left the ground white, as if it had snowed.

Today’s cold, wintry weather comes after yesterday’s strong cold front brought squally thunderstorms packing potential wind gusts up to 125km/h which swept across the South West and metropolitan area yesterday afternoon, hitting areas from Geraldton to Narrogin to Albany last night.

The State Emergency Service received 35 calls for help during and after the storm, mainly in the metro area for minor damage to homes and fallen trees on patios.

Heavy rain in South-West, Perth Hills

In the South West Forest Grove recorded 50mm, Cowaramup 47mm; Witchcliffe, just south of Margaret River, and Donnybrook had 43mm; Cape Naturaliste 33mm and Bunbury 27mm, with many centres receiving 20mm or more.

Further north, Dwellingup, 97km south of Perth, got 52mm; Bickley in the Perth Hills received a drenching with 67mm; Swanbourne 41mm and Jandakot 33mm. Perth city recorded 27mm and Perth Airport 31mm.

Most stations in the Hills received 40mm or more, with Pickering Brook 56mm; Karnet and Mundaring 46mm.

Strong winds buffeted most of the South West and the city with gusts recorded over 100km/h. Mandurah had a gust of 102km/h and Rottnest Island 96km/h.

Good rainfalls reached most of the Wheatbelt with farmers welcoming much-needed falls of 15mm to 30mm to boost yields on all grain crops.

In the Central West, Dandaragan had 24mm; Badgingarra 22mm, Northampton 18mm, Mingenew 17mm; and Morawa 11mm, with Geraldton Airport recording just over 8mm. But much of the region received 15mm or more.

In the Great Southern Wandering got 35mm, Williams 27mm, Katanning 25mm, Narrogin 24mm, Brookton 21mm and Lake Grace 10mm.

In the Central Wheatbelt, where farmers are desperate for rain, York got 26mm, Wongan Hills 17mm; Northam 16mm.

Sheep farmers warning

Sheep farmers in the Lower West, Great Southern, Southwest, South Coastal,Southeast Coastal, and the southern parts of the Central Wheat Belt and Central West districts are advised that wet and windy conditions are expected during Tuesday as a deep low pressure system moves to the south of the state. There is a serious risk of sheep or lamb losses.

Today Hailstorm South Africa State of Gauteng, Johannesburg Damage level Details

Hailstorm in South Africa on Thursday, 06 September, 2012 at 05:34 (05:34 AM) UTC.

Description
A hailstorm has battered Johannesburg, with several road accidents being reported. Radio 702’s early morning show has been inundated with calls and SMSes from people reporting heavy hail and rain. Several said road conditions were very poor and urged motorists to drive with extreme caution. Presenter Ray White said he had heard of a fatal accident in Randfontein. A caller said she was stuck behind a three-car pile-up. One man, calling from Rosebank, said: “It’s white, white, white.” Another woman said that even though she was driving at 50km/h, her brakes were not working because of the slipperiness of the roads. On Twitter at 5.57am, the SA Weather Service posted this warning: “Severe thunderstorm over N. Joburg and Centurion with possible heavy falls that might lead to road flooding within the next 30min.”
Today Flash Flood USA State of Massachusetts, Fall River Damage level Details

Flash Flood in USA on Thursday, 06 September, 2012 at 04:48 (04:48 AM) UTC.

Description
Heavy rain and a high tide caused flooded streets in Fall River on Wednesday. Trucks, cars and ambulances tried to navigate streets that looked more like rivers. Flash floods forced people to abandon cars and even trapped some people inside Bruce Morrow’s sporting goods store. “We were inside and people all of a sudden the people inside said, ‘Hey the water is coming in the doors,’” said Morrow. Close to 40 people were trapped in the store during the torrential downpour and flash flooding. “He told us we could leave, but where were we going to go? Honestly, the water was all the way up. Where were you going to go? Swim across to a truck that’s submerged?” said Melonie O’Brien, who was trapped in the store. Some drivers plowed through flooded streets, leaving small wakes in their path. Roads were closed; cars were diverted or abandoned in the middle of the madness. “My car is here. Now I have to walk to work because I can’t get by anywhere,” said Shannon Sousa, who abandoned her car. “Just made it here, but all over it’s completely flooded. It’s ridiculous. It’s like the whole city is shut down right now.” The ramp to 24 at Exit 8A was waterlogged and closed to traffic. The only way people were getting around at the height of the storm was on foot and without shoes. Everything in the town was soaked. “This is the worst it’s ever been in the last 22 years since we’ve been here. Just two weeks ago it was almost this bad. This is the worst,” said John Norfolk, who is cleaning up after his store flooded. The Red Cross is on the scene trying to help some of the stores and businesses that have been drenched with the torrential rains.
Today Flash Flood Pakistan Multiple areas, [Karachi (Sindh), Lahore (Punjab)] Damage level Details

Flash Flood in Pakistan on Thursday, 06 September, 2012 at 03:13 (03:13 AM) UTC.

Description
Torrential rains and floods yesterday killed at least 15 people in Pakistan, officials said. Pakistan-administered Kashmir in the north and the southern port city of Karachi were among the worst-hit areas. Police officer Malik Shafiq said “13 people, including three women, were swept away” by a flooded stream in Machhera village, about 35kms from the Kahmir capital Muzaffarabad. “So far we recovered one body while efforts were underway to find others,” Shafiq said. Rescue work was underway, he added. He adding there were also reports of landslide in the area. “The water level is still very high and has hampered the rescue operation. It seems that there is no chance for any survival,” Ansar Yaqoob, a senior government official added. Two people died when the roof of their house collapsed due to rain in the Hafizabad district of Punjab province. Police said more people were still trapped under the debris. In Karachi, prolonged power cuts and gridlocks were reported after heavy rainfall as officials struggled to restore electricity to the financial hub with a population of more than 18mn. Chief meteorologist Arif Mehmood said his department had forecast heavier monsoon rains than the previous year.

Epidemic Hazard in New Zealand on Wednesday, 05 September, 2012 at 14:02 (02:02 PM) UTC.

Description
Five people in the Auckland region have been diagnosed with potentially fatal meningococcal disease in the past week. Auckland Regional Public Health Service said no-one had died from it and no links between the cases had been established. Since January, 16 people in Auckland have contracted meningococcal disease – less than the 23 patients diagnosed with it during the same period in 2011. The last death from meningococcal disease reported in Auckland was in August last year. Meningococcal disease can be life threatening if it is not treated early. The health service is encouraging Aucklanders to remain alert for flu-like symptoms that become worse within two or three days. On Monday, a Wellington teenager died from suspected meningococcal disease. It is the first suspected meningococcal death in that region this year. Amanda Crook-Barker had the day off school after feeling “a little bit sick”. The 12-year-old vomited in the morning and developed a rash around 3pm. Ambulance staff were called after her symptoms worsened and she died in hospital at 5pm.

Meteoroids Change Atmospheres of Earth, Mars, Venus

Nola Taylor Redd
Space.com

Perseid Meteor

© Jeff Berkes
Astrophotographer Jeff Berkes caught this Perseid meteor over the Hawaiian island of Kauai in 2010.

Meteoroids streaking through the atmospheres of planets such as Earth, Mars and Venus can change these worlds’ air, in ways that researchers are just now beginning to understand.

Most planetary atmospheres are made up of simple, low-mass elements and compounds such as carbon dioxide, oxygen and nitrogen. But when a debris particle, or meteoroid, passes through, it can shed heavier, more exotic elements such as magnesium, silicon and iron.

Such elements can have a significant impact on the circulation and dynamics of winds in the atmosphere, researchers say.

“That opens up a whole new network of chemical pathways not usually there,” said Paul Withers of Boston University.

Contaminating the outer layers

Part of a planet’s upper atmosphere, the ionosphere contains plasma – a mixture of positively charged (ionized) atoms or molecules and the negatively charged electrons stripped from them. When simple elements such as oxygen move into this outer shell, they break apart easily, decaying in a matter of minutes.

But meteoroids streaking toward a planet’s surface carry heavier metals that can be removed in a variety of ways. A grain of dust, for instance, may rapidly burn up, shedding already-ionized magnesium as it falls. Or, neutral magnesium may be torn from the small rock, then receive a charge from sunlight or from stripping an electron from another particle. The newly charged elements can take as much as a full day to decay.

Meteoroids that blaze a trail through the atmosphere are called meteors, or shooting stars. Only those that make it to the ground are meteorites.

“When we add metal ions to the ionosphere as a result of this meteoroid input, we create plasma in regions where there wasn’t any plasma there to start out with,” Withers told SPACE.com.

In a recent article for Eos, the American Geophysical Union’s newspaper covering Earth and space sciences, Withers discusses important questions raised by the recent wealth of research on the upper atmosphere of Mars and Venus.

Shocking similarities, strange differences

Over the last decade, scientists have collected more and more information about the ionospheres of Mars and Venus. Though one might envision the composition and location of the two planets would create different interactions in the ionosphere, the two are actually very similar, scientists say.

“If you stand at the surface of the two planets, they are very different,” Withers said. “But up at about 100 kilometers (62 miles), conditions are surprisingly similar.”

The pressures, temperatures, and chemistry at high altitudes are comparable for the two planets. So too are many of the properties of the layers of charged particles shed by meteoroids.

“The plasma densities are quite similar on average on all three planets, which is not what you might expect on the first impression,” Withers said, referring to Earth, Mars and Venus.

Since the sun is the ultimate driving force for most ionization processes, it’s tempting to assume that Venus has more particles in a given area than Mars does because it orbits twice as closely to our star. Instead, the two planets have similar densities, which differ from Earth’s measurements by only a factor of ten.

At the same time, the layers affected by the meteoroids on Earth are very narrow, maybe only a mile or two wide, while Venus and Mars both have layers stretching six to eight miles.

According to Withers, the difference may come from the presence of Earth’s strong magnetic field, a feature lacking on the other two planets. But scientists aren’t certain how much of a role the field actually plays.

Finding the source

To study Earth’s ionosphere, scientists can launch rockets to take measurements in the region. But the process is more complicated for other planets.

As a spacecraft travels through the solar system, a targeted radio signal sent back to Earth can be aimed through the ionosphere of a nearby planet. Plasma in the ionosphere causes small but detectable changes in the signal that allow scientists to learn about the upper atmosphere.

This process – known as radio occultation – doesn’t require any fancy equipment, only the radio the craft already uses to communicate with scientists on Earth.

“It’s really one of the workhorse planetary science instruments,” Withers said.

Because it is so simple, the process has been applied to every planet ever visited by spacecraft.

Only in recent years has enough data come back on Venus and Mars to seriously examine their upper atmospheres. As of yet, no numerical simulations have been created to explain some of the differences, but Withers expressed hope that this would change in the near future. Such simulations could help answer some of the questions that the observations have raised.

Withers also hopes that, in time, a detailed understanding of the ionosphere could even help scientists engage in a kind of “atmospheric archeology” for Venus and Mars.

One day, scientists may be able to track the history of comets in the solar system by measuring how planetary atmospheres have been affected by the icy wanderers’ shed dust and gas. But conclusions drawn by this sort of sleuthing are probably a ways down the road, Withers said.

05.09.2012 Biological Hazard Vietnam MultiProvinces, [Provinces of Haiphong, Ha Tinh, Ninh Binh, Nam Dinh, Bac Kan, Thanh Hoa and Quang Ngai] Damage level Details

Biological Hazard in Vietnam on Wednesday, 05 September, 2012 at 13:32 (01:32 PM) UTC.

Description
A new strain of avian flu virus that was found in China two months ago has appeared in Vietnam, health experts have confirmed. The new strain, 2.3.2.1 C, which has been detected through epidemic investigations, is highly toxic and therefore extremely deadly, Diep Kinh Tan, Deputy Minister of Agriculture and Rural Development, said at a meeting on September 4 to review the epidemic situation. The 2.3.2.1 C strain has recently spread to Vietnam and is now present in affected areas in seven provinces and cities, namely Haiphong, Ha Tinh, Ninh Binh, Nam Dinh, Bac Kan, Thanh Hoa and Quang Ngai, said Hoang Van Nam, head of the Department of Animal Health (DoAH). As the new strain is different from the A/H5N1 virus, the ministry is to conduct experiments and tests to confirm if the vaccines that are being used to combat A/H5N1 are also effective against the new strain.If the existing medication is ineffective, studies on new vaccines against the new strain should be conducted soon, Tan said, adding that he has asked the DoAH to isolate the virus for this purpose. The Central Veterinary Diagnosis Center is also monitoring and looking into the new strain to help find a specific medication against it. The avian flu has so far this year severely impacted the seven above-mentioned provinces and cities, with more than 181,000 ducks and chicken having died or been culled, the DoAH reported. Most of these provinces are involved in smuggling poultry from China that might have carried pathogens that were then spread to domestic poultry, the department said.
Biohazard name: H5N1 (2.3.2.1 C) – Very highly pathogenic avian influenza virus – New strain
Biohazard level: 4/4 Hazardous
Biohazard desc.: Viruses and bacteria that cause severe to fatal disease in humans, and for which vaccines or other treatments are not available, such as Bolivian and Argentine hemorrhagic fevers, H5N1(bird flu), Dengue hemorrhagic fever, Marburg virus, Ebola virus, hantaviruses, Lassa fever, Crimean-Congo hemorrhagic fever, and other hemorrhagic or unidentified diseases. When dealing with biological hazards at this level the use of a Hazmat suit and a self-contained oxygen supply is mandatory. The entrance and exit of a Level Four biolab will contain multiple showers, a vacuum room, an ultraviolet light room, autonomous detection system, and other safety precautions designed to destroy all traces of the biohazard. Multiple airlocks are employed and are electronically secured to prevent both doors opening at the same time. All air and water service going to and coming from a Biosafety Level 4 (P4) lab will undergo similar decontamination procedures to eliminate the possibility of an accidental release.

Description
Tens of thousands of rotting fish are lining a 40-kilometre stretch of shoreline along Lake Erie, reports the provincial environment ministry, which is investigating the cause. A spokesperson for the Ontario Ministry of Environment said Tuesday the kill was reported on the weekend. So far it appears the fish may have died from the affects of a naturally occurring lake inversion rather than a spill, but cautioned the investigation is continuing. The question now is which agency is responsible for cleaning up the rotting carcasses of thousands of yellow perch, carp, sheepshead, catfish, big head buffalo and suckers, which kept untold beachgoers from enjoying their Labour Day weekend. “It (the water) was quite putrid really … I had never experienced anything like this,” said Neville Knowles, of London, Ont. and cottager at Rondeau Provincial Park for more than 50 years. The dead fish stretch from west of the fishing village of Port Stanley in Elgin County to the village of Morpeth in Chatham-Kent or just east of Rondeau. “There was a significant number of fish, tens of thousands,” the environment ministry’s Kate Jordan told the Star. Jordan said the ministry officials took fish and water samples for analysis, “but all observations made at the site … did not show anything unusual and we did not see any evidence of … a spill to the lake or man-made pollution … so we are considering natural causes, including a lake inversion.” She explained that an inversion happens when the surface water cools down dramatically, sinks and displaces the bottom layer, which has lower oxygen content. As the bottom layer is displaced, it rises and robs fish of oxygen needed to survive. The phenomenon is also referred to as the lake “rolling over.” Even so, some residents are suspicious just the same that run-off from a large pig operation along the stretch may have caused the fish to die, said Knowles, who quickly added there is nothing to support that position.

Description
The Coast Guard is investigating about 90 reports of oil and chemical releases associated with Hurricane Isaac, including a leak from a closed storage facility in Plaquemines Parish that killed several brown pelicans, officials said Tuesday. Separately, the Louisiana Department of Wildlife & Fisheries closed a stretch of coastline from Elmer’s Island to Belle Pass after a tar mat appeared in the Gulf of Mexico and tar balls washed ashore. The closure affects commercial and recreational fisheries from the shore to one mile offshore. The agency and Department of Environmental Quality will determine the source of the oil, but its location has stoked concerns that it is remnants of the 2010 Deepwater Horizon explosion and subsequent oil leak. The Coast Guard did not address Tuesday’s coastal closure, which happened hours after senior officers, including Coast Guard Commandant Adm. Robert Papp, held a press conference at Coast Guard Sector New Orleans’s headquarters in Algiers. But Coast Guard officials said that in addition to causing new spills, hurricanes do stir up oil resting the seabed. “It often happens, particularly down here in the Gulf area,” Papp said. Oil samples have been sent to a Coast Guard laboratory in New London, Conn., for analysis, which is expected to take a week, Lt. Lily Zepeda said. The Coast Guard is responding to “several different reports of oil,” including at Myrtle Grove in Plaquemines Parish, said Rear Adm. Roy Nash, commander of the 8th Coast Guard District, whose headquarters is in New Orleans.A “defunct” terminal with storage tanks at Myrtle Grove leaked oil that has been contained, said Capt. Peter Gautier, commander of Coast Guard Sector New Orleans and captain of the port of New Orleans. But the oil contaminated seven or eight brown pelicans. “Several of those are dead,” he said. Other reports range from lose barrels to overturned rail cars and tanks that are not leaking, Gautier said. He also cited a chemical release in Braithwaite, the scene of some of Isaac’s most serious flooding that left two people dead and scores of others homeless when the storm surge topped a parish-owned levee. Incidents reported to the Coast Guard’s National Response Center last week include an oil storage barge carrying 1,646 barrels of crude oil that was missing from an oil production facility in Barataria Bay; a discharge from an offshore platform near South Pass; and a release from a platform near High Island because of an equipment malfunction after the platform was evacuated. U.S. Sen. Mary Landrieu, D-La., also at the press conference, called Isaac’s hovering on the region for 60 hours “unprecedented.””It could have been a lot worse, considering he infrastructure,” Landrieu said of the region’s petroleum industry. She also used Isaac to renew her call to provide hurricane protection to communities such as Venice in Lower Plaquemines, home to people who work in the offshore industry and maritime commerce. “This is a very strategic area for the United States of America,” Landrieu said. Papp, the senior most Coast Guard officer, said he traveled to the Gulf Coast “to thank my Coast Guard people” for their response to Isaac. He also said Coast Guard personnel stationed in the region were impacted by the storm like everyone else.

Today Technological Disaster China Province of Hubei, Wuhan [Qiaokou district] Damage level Details

Technological Disaster in China on Thursday, 06 September, 2012 at 04:51 (04:51 AM) UTC.

Description
A cave-in at a construction site injured eight workers and trapped at least one other in Wuhan, Hubei province, on Wednesday, local authorities said. The collapse happened at 7:30 am in the underground structure of a planned market for home furnishings and building materials in Qiaokou district. A staff member of the market, who declined to give a name, said that the workers were pouring concrete over the roof of the building when the collapse happened. At least one worker remained trapped in the rubble and a search by three teams of firefighters continued, said an official surnamed Tong from the fire control department of Wuhan on Wednesday. The cave-in caused a clutter of steel bars and concrete that made the rescue work difficult, Tong said. Eight injured people pulled from the debris were sent to Wuhan No 10 Hospital for treatment. Six workers were slightly injured and two critically, a doctor at the hospital said. A resident surnamed Wang who lives near the construction site said that he heard a loud bang and felt a tremor when the site collapsed. The construction company for the project is Zhejiang Baoye Construction Group.
