San Miguel volcano news & activity updates

San Miguel volcano (El Salvador) activity update

Friday Jan 15, 2016 11:20 AM | BY: T

Degassing from San Miguel volcano yesterday (MARN)
Degassing from San Miguel volcano yesterday (MARN)
The volcano continues to show strong degassing with light ash content, generating a plume that rises up to 1500 m from the crater and is being blown westwards.
Tremor amplitude remains elevated.
An image showing a pyroclastic flow allegedly from yesterday morning, circulating in some places and news articles, seems to be false.

The source said in its official Twitter account that the "freeing" of the volcano began at 5:20 local time (11:20 GMT) and the elevation of ash emitted by the crater ranges between 1,200 and 1,500 meters.

The seismic amplitude (MARS) volcano is at 1,244 units, when the normal level is 50 units, the ministry said.

Civil Protection director Jorge Melendez, with the mayor of San Miguel, Miguel Pereira, moved to the communities near the volcano to verify the conditions of the locals.

"The Chaparrastique is an active volcano (...) we do not expect a more serious situation that presented, we will continue monitoring and informing the population, which is quiet," said the head of Civil Protection.

Pereira said communities in San Jorge, San Rafael, San Miguel and Chinameca, near the crater, were authorized by "any emergency that may happen in the coming hours."
