Roundup of Global Volcanic Activity

Karangetang (Siau Island, Sangihe Islands, Indonesia): Activity at the volcano has decreased a bit, judging from the overall thermal signal, but continues with slow lava extrusion and small explosions at the summit crater, generating incandescent avalanches. The alert level is kept at 3 (out of 4). VSI in its latest bulletin from 11 Nov mentioned that there is no significant increase or decrease of activity based on evaluation of visual and instrumental observations.

Bromo (East Java, Indonesia): A phase of increased unrest seems to have started at the volcano. On 1 November, the local volcano observatory issued a warning not to approach Bromo within 1 km radius, as changes in seismic activity and increased steaming/degassing (including sulfur dioxide) had been noted. The alert status of the volcano remains at 2 ("waspada","watch") on a scale of 1-4.
