Volcanos

Roundup of Global Volcanic Activity

Nishino-shima (Volcano Islands): An explosive event occurred last night at the growing island volcano. VAAC Tokyo reported an ash plume at 10,000 ft (3 km) altitude drifting to the northeast.

Sinabung (Sumatra, Indonesia): An unusually large collapse of parts of the still active lava flow occurred last night at around 19:30 local time and produced a large, dangerous pyroclastic flow that traveled approx. 4.5 km to the SE. There are no reports of injuries or fatalities, hopefully because no one was in the affected part of the exclusion zone. The flow had stopped in the immediate vicinity of the evacuated villages Berastapu and Sukanalu.

The collapse developed from the second lobe which has been active on the upper, steeper, and thus more prone to collapse, part of the slope on top of the older lobe. The pyroclastic flow also gave rise to an ash plume rising approx. 4 km.

Ubinas (Peru): A moderately sized vulcanian-type (sudden, vent-clearing) explosion occurred at the volcano this morning at 09:00 local time. An ash plume rose approx. 2 km from the crater and drifted east.
