San Miguel ( Chaparrastique ) , El Salvador : small explosions in the volcanic conduit.

Special Report No. 5: The recorded seismic activity on the volcano Chaparrastique has subtle changes.
Friday, March 18, 2016 5:18 p.m.

From 7:00 Wednesday, March 16, until the publication of this report, the seismic vibrations of the Chaparrastique volcano continued to show fluctuations. The network of seismic stations recorded since yesterday morning, the occurrence of earthquakes associated with small explosions in the volcanic conduit.
In the last 24 hours, the seismic tremor has fluctuated between 131 and 192 units RSAM / hour, with an average of 156 units, the maximum threshold of normal behavior is 150 units.

The images captured by the surveillance camera located on the Cerro El Pacayal show that the top of the volcano is still very cloudy most of the time, however, for short periods, emission of small gas pulses from the crater were observed, which do not exceed more than 150 meters, and rising rapidly dissipate under the influence of winds. Meanwhile, the network of local observers did not report anomalies in the region.

The network of seismic stations registered on the volcano between 04 h 23 and 05 h 15 this morning, the presence of six seismic signals associated with small bubble bursts inside the volcanic conduit.
These small earthquakes were located on the north side of the volcano with magnitudes between M1,4 and M1, at depths of less than 1 km.

The MARN continues its enhanced surveillance of the volcano, maintains close communication with the General Directorate of Civil Protection and local observers.
These periodic changes in the volcano’s behavior indicates that it remains active, without excluding future activity, either by the central crater or his flanks.
MARN invites journalists and people not to approach the summit of the volcano, because of the degree of danger it presents.
