The volcano continues to have strombolian to vulcanian explosions. Some of them are large enough to produce ash plumes visible on satellite imagery, such as one on 28 Feb (ash plume to 7,000 ft reported by VAAC Tokyo). [more]

Although no larger explosions or dome collapses have occurred in the past days, the activity at the volcano remains intense and such events could happen any time again. The clear weather today showed the active lava dome still grows on both sides, produces smaller avalanches and an intense steam plume that sometimes contains volcanic ash: ... [more]

Activity at the volcano remains elevated. The lava dome extrudes currently 2 lobes of viscous lava, a larger one on the NW side and a smaller one on the SE side, which seems to have appeared around 16 Feb. The active parts of the dome suffer frequent small to moderate-sized avalanches (mainly from the NW side). Bright glow can be seen at night. ... [more]

A phase of intense activity has been taking place at the volcano over the past few days. On 6 Feb afternoon (or early morning 7 Feb in Kamchatka), a large eruption occurred. VAAC Tokyo spotted an ash plume drifting at approx. 27,000 ft (9 km) altitude more than 300 km northwest. The ash plume reached the Sea of Okhotsk and ash fall occurred in the village Sedanka at more than 200 km distance from the volcano. ... [more]

On 31 Jan, KVERT finally lowered the Aviation Color Code of the volcano back to green, as the volcano has been calm for a while and shows no more signs of unrest that new activity could be likely in the near future. ... [more]

A new eruptive phase appears to have started at the volcano. VAAC Tokyo reported continuous ash emission and an ash plume drifting north at estimated 16,000 ft (5 km) altitude. ... [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.
