New explosion of ash at Costa Rica’s Turrialba Volcano

L. Arias

Costa Rica’s Turrialba Volcano, located 50 kilometers east of San José, erupted at 1:12 p.m. on Monday and launched ash and vapor into the air for about 10 minutes, experts with the University of Costa Rica (UCR) and the National University (UNA) reported.

This is the second event this month after another 10-minute explosion recorded on Dec. 7. also spewed ash and gases into the air.

Experts from UNA’s Volcanological and Seismological Observatory of Costa Rica (OVSICORI) reported the explosion reached just under 400 meters in height.

UCR’s Mauricio Mora at 2:30 reported there were no more explosions. Mora was conducting an inspection in the volcano’s surrounding areas and said experts are evaluating whether the explosion was an isolated event or is part of an eruptive process.

Residents from communities near Ecuador’s Tungurahua volcano faced a massive cleaning operation on Thursday (19 November) after the volcano erupted, covering houses and fields with smoke and ash. Authorities issued an orange alert as emissions reached 2,500 metres above the crater.

In nearby Queros, one of the most affected communities, officials registered 10kg of ash per square metre.

As he swept the street near his house, resident Luis Vaca said the volcanic material was damaging crops. “Ash is falling everywhere; it’s strong, especially in the countryside where it’s falling more heavily. It’s damaging the crops. It would be good if the president came to visit us,” he said.

Volcano Eruption Chile Antofagasta Region, [Lascar Volcano] Damage level Details

……….

Volcano Eruption in Chile on Friday, 30 October, 2015 at 17:28 (05:28 PM) UTC.

Description
Lascar, in the northern Andes of Chile, erupted unexpectedly today, producing a small plume of light grey ash that reached 2.5 kilometers (~8,200 feet) above the volcano. The fact that there seemed to be little in the way of precursory activity (earthquakes, increased gas emissions) from Lascar suggests that this blast may have been a phreatic explosion driven by water flashing to steam in the volcano’s summit crater or conduit. Due to this minor eruption, the SERNAGEOMIN has raised the alert status at Lascar to Yellow, although the volcano is in a fairly remote part of the Chilean Andes-the Global Volcanism Program reports only ~8,100 people living within 100 kilometers (62 miles) of Lascar. It has been over 2 years since Lascar last did anything and its last major eruption of Lascar was in 2005. However, it has produced some spectacular eruptions in the recent past, including the 1993 eruption that was a VEI 4. As with any of these small blasts, volcanologists will watch Lascar to see if this is a sign that it is awakening or merely a blip. Based on images on the Lascar webcam, the eruption appears to have waned rapidly.

Lascar, in the northern Andes of Chile, erupted unexpectedly today, producing a small plume of light grey ash that reached 2.5 kilometers (~8,200 feet) above the volcano (see above). The fact that there seemed to be little in the way of precursory activity (earthquakes, increased gas emissions) from Lascar suggests that this blast may have been a phreatic explosion driven by water flashing to steam in the volcano’s summit crater or conduit.

Due to this minor eruption, the SERNAGEOMIN has raised the alert status at Lascar to Yellow, although the volcano is in a fairly remote part of the Chilean Andes—the Global Volcanism Program reports only ~8,100 people living within 100 kilometers (62 miles) of Lascar.
