MODIS thermal signal from Karangetang (MIROVA)
Activity at the volcano has decreased a bit, but the volcano continues to effuse viscous lava at its summit, feeding a lava flow and generating incandescent avalanches.
from the Smithsonian / USGS Weekly Volcanic Activity Report 4-10 November 2015:
During 28 October-4 November that activity remained stable. The lava dome was incandescent at night and produced a lava flow that traveled 200 m S. Incandescent avalanches from the lava-flow front traveled as far as 2 km E down the Batuawang and Kahetang drainages.
Seismicity decreased, but continued to be dominated by avalanche signals. The Alert Level remained at 3 (on a scale of 1-4); visitors and residents were warned not to approach Karangetang within a 4-km radius.
