Volcanos

Roundup of Global Volcanic Activity

Bagana (Bougainville Island, Papua New Guinea): Mild activity with occasional explosions seems to continue at the volcano. A volcanic ash plume to 7,000 ft (2.1 km) altitude was detected this morning extending 55 nautical miles to the NE (Darwin VAAC). A weak to moderate thermal anomaly has been recorded by MODIS satellite sensor over the past months.

Dukono (Halmahera): Strong, often near-continuous ash emissions continue at the volcano. Yesterday, VAAC Darwin reported an ash plume extending 70 km to the NE.

Telica (Nicaragua): A series of 5 moderately strong explosions occurred at the volcano yesterday and lasted half an hour. It produced dense ash plumes and ejected blocks to up to 500 m distance. According to Nicaraguan press, the activity is still phreatic and does not involve new magma, but it could be building up to a magmatic eruption. Authorities for the time being rule out evacuations, but have started to prepare for the case this would become necessary.
