Ash emissions from Chaparrastique volcano on 23 July (MARN)
Ash emissions from Chaparrastique volcano on 23 July (MARN)
New ash emissions occurred on 23 July, similar to the previous such episode on 13 July. Small plumes rose a few 100 m above the crater. Seismic tremor remains high and authorities keep a close watch on the volcano.

Tremor amplitude at Chaparrastique volcano over the past weeks (MARN)
Tremor amplitude at Chaparrastique volcano over the past weeks (MARN)
The volcano continues to produce important gas emissions as well as occasional small ash explosions. Tremor remains at very high levels (20 times above normal), caused by internal fluid movements. The likelihood of new eruptive activity in the near to medium future remains elevated.

Tremor amplitude at Chaparrastique volcano over the past weeks (MARN)
Chaparrastique volcano has started to produce small explosions and significant ash emissions. An increase of the ongoing eruption could occur any time and is expected to occur either from the summit vent or from the northern flank (because earthquakes have been clustered under this part of the volcano during the past months). ...more

Current seismic activity at San Miguel (VSM station, MARN)
Current seismic activity at San Miguel (VSM station, MARN)
Seismic activity remains at elevated levels and the volcano emits strong pulsating gas and steam puffs rising to approx. 800 m. Heavy rainfalls have been causing damage due to mud flows in the areas at the feet of the volcano. ...more
