Roundup of Global Volcanic Activity

Kliuchevskoi (Kamchatka): Mild strombolian activity and associated ash emissions continue from the summit crater of the volcano. Tokyo VAAC reported an ash plume to 20,000 ft (6 km) altitude on 8 May.

Karangetang (Siau Island, Sangihe Islands, Indonesia): An increase in activity occurred during the past days, resulting in dangerous pyroclastic flows that swept 3 km down the steep southern slope of the volcano. The cause was elevated strombolian activity combined with effusion of a viscous flow from the summit crater, which resulted in partial collapses of the lava flow. People living in villages near the volcano were evacuated and it seems no fatalities occurred, although houses in the village of Kora Kora were destroyed by the pyroclastic flow on 7 May. Significant ash fall occurred on the northern flank of the volcano.

Batu Tara (Sunda Islands, Indonesia): An ash plume was seen yesterday on satellite imagery extending 45 nautical miles to the west.

Dukono (Halmahera): Intense ash emissions continue at the volcano. Darwin VAAC reported a plume at estimated 10,000 ft (3 km) altitude extending 40 km to the east.

Telica (Nicaragua): Several small explosions with ash emissions have occurred from the volcano's summit vent since 8 May. 8 explosions generated ash plumes up to 250 m height that drifted west causing light ash fall in the villages Quebranchal, Telica, Polvareda and Las Joyas.
