San Miguel volcano news & activity updates

San Miguel volcano (El Salvador) activity update

Current seismic signal at San Miguel volcano (VSM station, MARN)
Current seismic signal at San Miguel volcano (VSM station, MARN)
No significant changes have occurred, but the authorities warn that another eruption in the near to medium-term future cannot be ruled out. Seismic activity with the presence of volcanic tremor remains at elevated, fluctuating levels. A degassing, SO2-rich plume rises about 150 meters above the crater.
Previous news
Wednesday, Jan 08, 2014
Chaparrastique (the local name of the volcano) is still restless. SNET reports seismicity at (low) levels similar to before and after the eruption on 30 Dec, and a degassing plume of 100 m height, with a decreasing tendency. However, new eruptions with little or no warning could occur and authorities ask people not to approach the crater. [more]

Thursday, Jan 02, 2014
No new explosions have occurred at the volcano of Chaparrastique (San Miguel), but elevated degassing (SO2 flux estimated at about 2800 tons / day) suggests that new magma is still arriving inside the volcano and could lead to new eruptions. ... [more]
