San Miguel volcano (also known locally as Chaparrastique) in eastern El Salvador is a symmetrical stratovolcano and one of the most active volcanoes of the country. It rises majestically from near sea level to 2130 m elevation and forms a prominent land mark.
The volcano's summit lacks vegetation due to frequent eruptions, but its flanks are largely covered with coffee plantations.
San Miguel has a broad, deep crater complex, which has frequently changed morphology during historic eruptions recorded since the early 16th century.

Current seismic signal from San Miguel (VSM station, SNET)
Seismic unrest (fluctuating, sometimes strong volcanic tremor and earthquakes) continue. Several hot spots are visible on the volcano's flanks, but most likely caused by fires.
Strong tremor pulses and frequent small quakes and long period events appear on the seismograms of San Miguel volcano. ...more
SNET has not reported other unusual activity from the volcano and maintains its safety recommendation to stay away 2 km from the summit, which was issued in July 2011 when seismicity started to increase. [less]

Strong tremor pulses appear at the seismic recording of San Miguel volcano suggesting magma might be moving under the volcano. There are no reports of usual surface activity.
Yesterday's seismic signal from San Miguel (SVM station)
In El Salvador, San Miguel volcano is showin increased seismic activity. ...more
This somewhat “normal” behaviour for the volcano usually takes place over a period of several weeks to months time. Seismicity builds from low levels to nearly continuous strong tremor, often interspersed with felt events near its culmination. Little surface activity occurs in conjunction with each crisis, other than small, intra-crater rockfalls and increased outgassing. The volcano then slowly (again, weeks to months) returns to its relatively docile state. (Source: Earthquake-Report) [less]
