San Miguel (Chaparrastique) volcano (El Salvador): increasing volcanic unrest

Warning signs of a possible new eruption of the volcano in the near future are becoming increasingly alarming. Accompanied by an ongoing earthquake swarm, tremor (as an indicator of internal pressure) continues to climb. Pulsating gas emissions reaching 50-400 m height above the crater have been seen recently.
Sulfur dioxide (SO2) emissions remain high. Depending on wind direction and speed, air quality in downwind areas near the volcano often reaches unhealthy values.
Since 27 Jan, a total of 109 earthquakes were detected by MARN under the north flank of the Chaparrastique volcano, with magnitudes ranging between 0.6 and 1.9.

Sequence of the small explosion at San Miguel yesterday (MARN)
Thursday, Feb 13, 2014
A small ash explosion occurred yesterday afternoon at the volcano, at 16:44 (local time). It only lasted about 10 minutes and produced a small ash plume rising approx. 500 m. It is the first eruptive activity since the larger explosion on 29 Dec past year, and is likely only a precursor of more violent activity to come. ... [more]

Monday, Feb 03, 2014
The volcano has not erupted again, but shows increased signs of unrest. Since late January, the volcano's seismic activity has been rising significantly. MARN detected a swarms of earthquakes at very shallow 1 km depth beneath the SW flank, while a smaller number of quakes occured at approx. 6 km depth beneath the summit of the volcano. ... [more]
Current seismic signal at San Miguel volcano (VSM station, MARN)
Monday, Jan 13, 2014
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. [more]
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]
