Sequence of the small explosion at San Miguel yesterday (MARN)Kelud (East Java): It seems that a large eruption started at the volcano at 23:29 local time today. VAAC Darwin reports an ash plume to 45,000 ft (15 km) altitude is drifting 50 nautical miles to the west of the volcano. The alert status was raised to the highest level.
Local news suggest heavy ash fall (up to gravel sized) in distances of 15-40 km. Volcanologists on duty at the VSI observatory post left because to the danger posed by the eruption; Indonesian Civil Defense (BNPB) urged people living within 10 km of the volcano to evacuate. Indonesian government set up more than 70 evacuation shelters in areas around the volcano.
San Miguel (El Salvador): A small ash explosion occurred yesterday afternoon at the volcano, at 16:44 (local time). It only lasted about 10 minutes and produced a small ash plume rising approx. 500 m. It is the first eruptive activity since the larger explosion on 29 Dec past year, and is likely only a precursor of more violent activity to come.
Seismic activity has been increasing constantly over the past weeks, and clusters of earthquakes have been taking place at shallow (1 km) depth beneath the northern flank, MARN scientists measured. Tremor, indication of internal fluid (magma) movements and/or pressure, has been rising in intensity. As well, increasing values of sulfur dioxide (SO2) degassing suggest that new magma is rising within the volcanic edifice.
