San Miguel volcano (San Salvador): increase in seismic activity

Microseismic activity at Chaparrastique volcano (SNET)
Microseismic activity at Chaparrastique volcano (SNET)
During the past 2 days, seismic activity at the volcano has shown a sharp increase after it had been gradually decreasing since late February.
The latest bulletins published by SNET suggest that the most likely expected eruption would be strombolian-type with associated lava flows, probably on the north side of the volcano.
Even without an eruption, the volcano poses a serious risk of mud flows and landslides that could occur as a result of heavy rainfalls.
At the moment, the only visible activity at the Chaparrastique volcano remain pulsating gas emissions, but surveillance remains at a maximum. Authorities started to establish a plan for evacuation and relocation of about 280 families living in high risk areas around the volcano.
