Volcanos

Roundup of Global Volcanic Activity

Shiveluch (Kamchatka): A powerful explosion occurred at the volcano today (24 Sep) at 12:41 local time, producing an ash plume that rose to 38,000 ft (11 km) altitude. It generated several pyroclastic flows, some of which surpassed the 350 m high western caldera wall. The volcano had been relatively quiet during the past months. This morning's explosion could have been a result of gas pressure that slowly build up under the lava dome's plug of viscous lava. KVERT raised the alert level to red, and lowered it back to orange afterwards as no new eruptions followed and the ash had dissipated.

Zhupanovsky (Kamchatka, Russia): Intermittent explosions continue. An eruption occurred last evening on 23 Sep, producing an ash plume rising to 14,000 ft (4.2 km) according to VAAC Tokyo.

Bagana (Bougainville Island, Papua New Guinea): The volcano is still in eruption. A volcanic ash plume was observed by VAAC Darwin on 20 Sep extending 50 km to the west.

Dukono (Halmahera): After a phase of probably lower activity during the past weeks, strombolian activity picked up again and sometimes produces ash plumes that rise to 2-3 km.
