The volcano continues to slowly extrude viscous lava at its dome. An ash plume was produced this morning that rose to 13,000 ft (4.2 km) altitude and drifted SE. Most likely, it had been caused by a small to moderately large collapse on the eastern flank: ... [more]

No significant changes in activity occurred recently. The volcano remains active. Slow lava-dome extrusion continues accompanied by ash explosions, incandescence, hot avalanches, and fumarolic activity. ... [more]

The volcano remains more active than average. Another series of strombolian to vulcanian-type explosions today produced ash plumes rising to estimated 7,000 ft (2.1 km) and drifting SE (VAAC Tokyo). [more]

Volcanoes of KamchatkaThe Kamchatka Peninsula (Russia) is one of the most volcanically active volcanic places on earth, second only perhaps to Iceland and Hawaii. In this part of the Pacific "Ring of Fire", there are over 100 active volcanoes (the Smithsonian Institution lists 109) and about 30 volcanoes that have erupted recently, in addition to hundreds of smaller monogenetic vents (i.e. that have formed during one single eruption)
The active volcanoes form a 700-km long volcanic belt from Shiveluch in the north to Kambalny in the south. The vigorous volcanism on Kamchatka, like that of the adjacent Aleutian and Kurile island arcs, is produced by the subduction of the Pacific plate under the E margin of the Eurasian plate.
During the past 10,000 years, at least about 30 very large (so-called Plinian) eruptions have occurred in Kamchatka, i.e. eruptions that have ejected more than 1 cubic kilometer of magma. With this record, Kamchatka is by far the place on earth with the greatest frequency of large explosive eruptions.
The most active volcanoes on Kamchatka are Klyuchevsky, Shiveluch, Karymsky and Bezymianny.
