Volcanos

Roundup of Global Volcanic Activity:

Etna (Sicily, Italy): Sporadic small ash emissions have reappeared from the New SE crater during the past days, although weather conditions did not often allow direct observation. Since about 4 days ago, tremor has been showing a slowly rising trend, although it is still at low levels.

Santiaguito volcano (Guatemala): strong explosion and pyroclastic flows. Another violent eruption occurred at the lava dome yesterday morning (21 Sep) at 8:30 local time. Accompanied by explosions, the Caliente dome suddenly produced a series of major pyroclastic flows triggered by collapse of accumulated viscous lava at the southeastern rim rim and flank of the dome. The flows descended on all sides of the lava dome.

Shikotsu (Hokkaido): The latest report of the Japan Meteorological Agency indicates some unrest at the caldera. Seismic activity accompanied by inflation were recorded under the western flank of Tarumai stratovolcano (the most active vent of the system, located on the SW rim of the Shikotsu caldera) between late June and early July this year.

Sinabung volcano (Sumatra, Indonesia) Since the eruptions on 15 and 17 September, the volcano has been calm, but VSI warns that new eruptions could follow.
