Earthquake hits northwest Argentina, kills one; injuries reported

A magnitude 5.9 earthquake struck northwest Argentina on Saturday, the U.S. Geological Survey reported, leaving at least one person dead, injuring several more and damaging homes, according to local media.

BUENOS AIRES: A magnitude 5.9 earthquake struck northwest Argentina on Saturday, the U.S. Geological Survey reported, leaving at least one person dead, injuring several more and damaging homes, according to local media.

“Homes collapsed, families have been left with nothing, schools have been destroyed. We have one fatality, who was crushed,” Hector Romero, mayor of El Galpon, some 160 km from the provincial capital of Salta, told a local radio station.

“Currently there is one woman dead and injured people are being treated at the local hospital,” said Ernesto Flores, undersecretary with Salta’s civil defence authority, according to state-run news agency Telam.

RSOE EDIS  Event Report

Biological Hazard in Argentina on Friday, 09 October, 2015 at 11:49 (11:49 AM) UTC.

Description
Laboratoria Azul in Argentina reported Tuesday that a young heifer that had died suddenly has tested positive for anthrax. Laboratoria Azul Co-Director Ramon Noseda said the heifer came from a herd of approximately 1,300 animals, the area where the herd is located in Buenos Aires Province, which has had past cases of enzootic anthrax. Noseda said that three other heifers died in a similar fashion and the problem was recognized by a veterinarian. Sanitary controls have been established. Anthrax outbreaks among cattle have been reported in the country seven times since 2006, the most recent taking place this year. Argentine officials have established vaccination requirements for ranchers, but there are some ranchers that fail to vaccinate their herds. The Merck Veterinary Manual states that anthrax is most commonly found in livestock animals, including sheep, goats, cattle and other herbivorous animals. The disease is able to be spread to the human population through contact or exposure to infected tissue from meat. They also report that soil can act as a reservoir for anthrax spores for several years. Anthrax often presents itself as a severe illness in humans and animals with the potential to be fatal.
Biohazard name: Anthrax
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.
Symptoms:
Status: confirmed

Volcano Activity in MultiCountries on Saturday, 22 March, 2014 at 05:22 (05:22 AM) UTC.

Description
SERNAGEOMIN raised the alert level of the volcano to orange yesterday after an increase in seismic activity. A pulse of volcanic tremor was detected that could indicate magma moving into the volcano’s plumbing system. On the surface, no unusual activity has been seen at the volcano so far, except that an increase in SO2 emissions (approx 2,300 tons / day) was measured. This supports the idea that magma has risen under the edifice. Whether this activity is followed by new eruptive activity remains to be seen. In most cases, intrusions of magma under volcanoes do never reach the surface, i.e. produce eruptions. ONEMI (Civil Defense) published a bulletin stating that civil alert remains at yellow for the highest risk areas, in particular the most proximal areas around the volcano itself, but also include the city of Alto Biobío located 40 km west of the volcano, because it is at the mouth of a valley that drains Copahue on the north side and therefore, a potential pathway for mud flows that could occur during an eruption.

Additional Commentary

The November 25, 2013 M7.0 earthquake (06:27:33 UTC) southwest of the Falkland Islands in the South Atlantic Ocean occurred as the result of strike slip faulting, on either a left-lateral fault striking ENE-WSW, or a right-lateral structure striking NNW-SSE.  The location of the earthquake, near the ENE-WSW trending plate boundary between the South America and Scotia tectonic plates, suggests it is likely associated with left-lateral faulting along this margin. At the location of this earthquake, the Scotia plate moves ENE with respect to South America at a rate of approximately 9.5 mm/yr.

The November 25, 06:27:33 earthquake was the largest of 5 M5+ events that occurred in a similar area over an approximate 2-hour period, including a M5.6 earthquake 24 seconds prior to the M7.0 mainshock. Though this region experiences moderate-sized earthquakes relatively frequently – 15 M5+ events have occurred within 250 km of the November 25 earthquake over the past 40 years – large events are fairly uncommon. The largest nearby earthquake over the same time period was a M6.6 event in September 1993, 210 km to the east of the November 25 earthquake.

Tectonic Summary

The July 15, 2013 Mw7.3 South Sandwich Islands earthquake occurred as a result of either east-west left-lateral or north-south right-lateral strike slip motion at shallow oceanic crustal depths. The earthquake occurred ~100km east of a complex plate triple junction between the South America, Antarctica, and Sandwich plates. The South America plate currently subducts beneath the Sandwich plate at a rate of ~13mm/yr while sliding past the Antarctica plate with left-lateral motion along the South Sandwich Fracture Zone at a rate of ~14mm/yr. Given the strike slip nature and location of the event, the earthquake likely resulted from relative motion between the South America and Antarctica plates. Several large earthquakes have occurred along this portion of the plate boundary, including events of Mw7.4 in January 2006 and Mw7.5 in October 1973.

Description
The 2,965m (nearly 10,000ft) volcano – which sits in the Andes cordillera – has so far only spewed gas, but thousands of minor earth tremors have been registered in the area. Chilean Interior and Security Minister Andres Chadwick said the increased activity could lead to an eruption and officials would evacuate 2,240 people, or 460 families, within a 25-kilometre radius. “This evacuation is obligatory; it’s not voluntary,” Chadwick told reporters. Stoll not everybody is willing to leave. “No. I do not want to leave because we have chickens and it isn’t easy to leave them and go to a shelter,” resident Florinda Lipiman told the news agency Reuters. In neighbouring Argentina the authorities had first declared a “yellow alert” but later revised it to the highest level. They have now ordered the evacuation of at least 600 people from the town of Caviahue to the neighbouring city of Loncopue where the crisis committee said than an eruption “can take place at any moment now” Fears run deep as Copahue’s new eruptive cycle began in July 1992 when the crater lake explosions ejected rock fragments, white dust, large amounts of green and yellow liquid sulphur. In July 2000 Copahue registered its largest eruption in 100 years. Eruption of lapilli, ash, and bombs occurred at the volcano. Bombs up to 13 cm in diameter were ejected more than 8 km from the summit, and ash fell 100 km away.

SANTIAGO/BUENOS AIRES — Chilean and Argentine authorities on Monday declared a red alert and ordered the mandatory evacuation of a 25-kilometer (15.5-mile) radius around the active Copahue volcano, which straddles the border between the two Andean nations.The volcano — located some 500 kilometers (310 miles) south of capital Santiago, between Chile’s Bio Bio region and Argentina’s Neuquen province — has seen increasing seismic activity in recent weeks but has not erupted, Chilean authorities said.

“This doesn’t necessarily mean the volcano will start erupting. But according to the Sernageomin (National Geological and Mining Service), the volcano is now in a process that could culminate in an eruption, for that reason we’ve issued a red alert and the evacuation,” Chilean Interior Minister Andres Chadwick told a nationally televised news conference.

Authorities estimated that some 2,240 people will be evacuated in Chile.
