Sarychev volcano (Kuril Islands), short summary & update

Sarychev volcano erupted violently starting 11 June 2009 until mid-end of June, producing a series of sub-plinian eruptions sending large gas and ash plumes to 10-14 km elevation, which drifted westward across the northern hemisphere. The most powerful eruptions occurred between June 11-16. No large ash explosions were noted after 16 June, but Sarychev continues to erupt and produce smaller gas and ash plumes.
There is no local volcano monitoring available on Sarychev island (which likely would have been destroyed by now), and information on its activity is based on satellite and pilot observations.
