Chaparrastique Spews More Ash, Volcanic Gases

Posted by feww on December 31, 2013

Chaparrastique Volcano in Eastern El Salvador is Still Spewing Ash and Volcanic Gases

Up to 5,000 people live near the volcano, and the authorities have so far evacuated more than 1,600 to emergency shelters, but many have refused to leave their homes on the volcano slopes.

“The Chaparrastique volcano is still producing gases combined with small emissions of ash, which is normal after an eruption,” said  El Salvador’s environment ministry.

The 2,130-m high volcano,  El Salvador’s third highest, ejected columns of smoke and ash up to 5km above the summit on Sunday

Chaparrastique, aka San Miguel volcano, located about 15km SW of San Miguel city (population: 180,000), and about 140 km east of San Salvador, the capital, showed signs of increased activity on December 13.

The eruption has so far deposited more than 10cm of ash in the nearby areas within the coffee-producing region, according to reports.

El Salvador

El Salvador sits along the Pacific Ring of Fire, close to Middle America Trench, and is subject to significant tectonic movement, causing frequent earthquakes and volcanic activity. The tiny country (population: 6.3 million) is home to at least 23 volcanoes.

Middle America Trench

A major subduction zone known for many large earthquakes, the Middle America Trench is a 2,800-km long oceanic trench in the eastern Pacific Ocean, extending from central Mexico to Costa Rica. The trench is the boundary between five tectonic plates, including the Caribbean, Cocos (and Rivera), Nazca, the North American and the South American plates.

Chaparrastique volcano eruption prompts evacuation of hundreds of communities

Civil protection authorities in El Salvador have imposed a 5-km exclusion zone around the San Miguel volcano, aka Chaparrastique, and are evacuating up to 5,000 villagers that live near the volcano.

The 2,130-m high volcano,  El Salvador’s third highest, ejected columns of smoke and ash up to 5km above the summit.

Chaparrastique, located about  15km SW of San Miguel city (population: 180,000), showed signs of increased activity on December 13.

The eruption has so far deposited more than 10cm of ash in the nearby areas within the coffee-producing region, officials said.

Major Disaster Declared in New Mexico

Posted by feww on October 30, 2013

New Mexico Declared Federal Disaster Area due to Severe Storms, Flooding and Mudslides

The White House has declared a major disaster exists in the State of New Mexico due to major losses and damage caused by severe storms, flooding, and mudslides during the period of September 9-22, 2013.

The worst affected areas are the counties of Catron, Chaves, Cibola, Colfax, Eddy, Guadalupe, Los Alamos, McKinley, Mora, Sandoval, San Miguel, Santa Fe, Sierra, Socorro, and Torrance.

Additional designations may be made at a later date if requested by the state and warranted by the results of further damage assessments, said FEMA.

October 2 Disaster Declaration for NM

On October 2, 2013, WH signed a separate Major Disaster declaration for NM due to severe storms and flooding  which occurred July 23-28, 2013.

The worst of the losses and damages caused by severe storms and flooding occurred in the counties of Bernalillo, Colfax, Luna, Sandoval, and Socorro and the Cochiti, Kewa (Santa Domingo), San Felipe, and Sandia Pueblos.

2nd Major Disaster Declaration for the Santa Clara Pueblo

A separate Federal Disaster Declaration was signed last week for Santa Clara Pueblo to supplement the Tribe’s efforts in the area affected by severe storms and flooding during the period of September 13-16, 2013.

Major Disaster Declaration for Santa Clara Pueblo

On September 27, 2013 the Santa Clara Pueblo (Indian Reservation) was declared a Federal Disaster Area due to losses and damages caused by severe storms and flooding during the period of July 19-21, 2013.

VolcanoWatch Weekly [9 July 2009]

Posted by feww on July 9, 2009

Volcanic Activity Report: 1 July – 8 July 2009

Source: Global Volcanism Program (GVP) – SI/USGS Weekly Volcanic Activity Report

New activity/unrest:

NOTES: A large sulfur dioxide plume and several thermal anomalies from Manda Hararo were detected in satellite imagery during 28-30 June. On 8 July, a scientist that visited the area reported fresh lava flows, an eruptive fissure that was about 5 km long, and gas emitting from multiple cones.

According to news articles, PHIVOLCS implemented increased monitoring of Mayon after a recent rise in seismicity. Incandescence in the crater and a slight increase in sulfur dioxide gas output over background levels were also noted. (Source: GVP)

The massive complex is 105 km long and 20-30 km wide, and represents an uplifted segment of a mid-ocean ridge spreading center.

A large sulfur dioxide plume and several thermal anomalies from Manda Hararo were detected in satellite imagery during 28-30 June. Thermal anomalies detected in satellite imagery indicated a surface lava flow in the Karbahi region. Karbahi is a graben area with numerous active faults, fissures, and basalt flows, NW of the center of the broad Manda Hararo volcanic complex. Preliminary data suggested that the eruption was larger than the previous eruption in August 2007. On 8 July, a scientist that visited the area reported fresh lava flows, an eruptive fissure that was about 5 km long, and gas emitting from multiple cones.

Geologic Summary. The southernmost axial range of western Afar, the Manda Hararo complex is located in the Kalo plain, SSE of Dabbahu volcano. The massive complex is 105 km long and 20-30 km wide, and represents an uplifted segment of a mid-ocean ridge spreading center. A small basaltic shield volcano is located at the northern end of the complex, south of which is an area of abundant fissure-fed lava flows. Two basaltic shield volcanoes, the largest of which is Unda Hararo, occupy the center of the complex. The dominant part of the complex lies to the south, where the Gumatmali-Gablaytu fissure system is located. Voluminous fluid lava flows issued from these NNW-trending fissures, and solidified lava lakes occupy two large craters. Lava flows from the Gablaytu and Manda shield volcanoes overlie 8000-year-old sediments. Hot springs and fumaroles occur around Daorre lake. The first historical eruption from Manda Hararo produced fissure-fed lava flows in 2007. (Source: GVP)
