Roundup of Global Volcanic Activity:
Etna (Sicily, Italy): The New SE crater has remained quiet over night, while tremor has risen a bit overall. The NE crater in turn shows intense degassing.
Klyuchevskoy (Kamchatka): Relatively strong ash emissions continue. This morning, the plume rose to about 27,000 ft (7 km) altitude, drifting NW.
Bagana (Bougainville Island, Papua New Guinea): New explosions occurred this morning. An ash plume rose to 10,000 ft (3 km) altitude this morning and drifted 20 nautical miles to the east (VAAC Darwin).
Sinabung (Sumatra, Indonesia): After a relatively calm period, a large vulcanian explosion occurred at the volcano this morning (04:30 GMT). VAAC Darwin reports an ash plume to 38,000 ft (12 km) altitude drifting 50 nautical miles to the NW. The eruption was preceded by a smaller one at midnight (GMT) with an ash plume altitude of estimated 18,000 ft (5.5 km). The volcano has been on red alert for 2 weeks and more than 17,000 people remain evacuated (for good reason!).
