Chirinkotan volcano (Kurile Islands, Russia): steam plume observed suggests new eruption

The remote volcano in the northern Kuriles is probably in eruption, the latest SVERT report and satellite images suggest. A plume of gas and steam, and possibly some minor amounts ash was seen with the MODIS sensor onboard the NASA Terra satellite this morning.
Satellite data also indicate that activity had likely already started in early May, because a small thermal anomaly can be traced back on archive pictures to 7 May. One should take into account that frequent dense cloud cover often prevents such observations, so activity could have started earlier than that.
It is not known what kind of activity is occurring at the volcano. Possibilities include some minor explosive (strombolian ?) activity at the summit, or lava flows that might be reaching the sea and produce the steam plume observed.
The last eruption of the volcano was (probably) in 2004.
