Growing unrest: El Salvador’s San Miguel may be stirring for another eruption

February 17, 2014 – EL SALVADOR – 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. –Volcano Discovery
