San Miguel (Chaparrastique), El Salvador : The strong degassing is carried by the wind and can affect the population .

The technicians of the Observatory of the environment continue to monitor the activity. Yesterday, two volcanologists repeated temperature measurements and sulfur dioxide from the crater. The determined temperature is below 100 degrees Celsius, although, according to the expert, Demetrios Escobar, it remains high.
Until yesterday, the gas plume from the crater was dense, but much less than on Saturday after the explosion which took place at 04:00.

It is no longer saturated with ashes as the first day, but the emission still contains gas cloud blown by the wind to the north and the west flank of the volcano.
The strong degassing is carried by the wind and can affect the population in the lower area of the volcano according to its direction, which is mainly to the southwest of the crater
These changes have presented evidence that the volcano is active. Fluctuations in controlled settings are saved and frequently observed, and indicate anomalies in the system.

Given the current activity, the emergence of new low to moderate amplitude explosions is not rejected. However, the monitored parameters continue to rise, the scenario could become an effusive eruption of magmatic material either through the central crater or on the slopes of the volcanic structure.

In the last 24 hours, the measurement of the seismic amplitude recorded at the seismic station VSM, located at 1,700 meters altitude on the north flank of the volcano fluctuated between 174-237 units RSAM / hour on average, with a average of 221.

The gases from the volcano’s crater are carried by the wind to the Southwest, so that communities living in the area may perceive the smell of sulfur. In response, the use of masks or wet tissues is recommended when noticed a smell of sulfur and it is advisable to try to leave the area.
This type of volcanic activity can continue, it is recommended not to be at the top of the cone because of the danger of ejected material fall by an explosion, as well as also because of the risk of breathing at high concentrations of magmatic gases in the crater area.

MARN continues its enhanced surveillance of the volcano, maintains close communication with the General Directorate of Civil Protection and local observers. MARN invites journalists and people not to approach the summit of the volcano, because of the degree of danger that this represents.
