Kamchatka, 56.65°N / 161.36°E
Current status: erupting (4 out of 5)
Shiveluch webcams / live data
last update: 24 May 2012 (strong explosive activity, large ash plumes up to 8-9 km altitude)
Typical eruption style: Highly explosive. Construction of lava domes and large pyroclastic flows caused by dome collapse. One of Kamchatka's largest and most active volcanoes.
Shiveluch volcano eruptions: 1739(?), 1800(?), 1854 (Plinian eruption), 1879-83, 1897-98, 1905, 1928-29, 1930, 1944-50, 1964 (sub-Plinian, large dome collapse and debris flow), 1980-81, 1984, 1985, 1986-88, 1988, 1989 1990-94, 1997, 1998, 1999, 1999-ongoing Shiveluch volcano on a Terra satellite image from 19 Feb 2012. Volcanic debris is seen on the lower flanks; the debris traveled about 10 kilometers (6 miles) from Shiveluch’s growing lava dome. (Nasa Earth Observatory)
Shiveluch (Sheveluch) volcano is one of Kamchatka's largest and most active volcanoes, and the one that has had the most violent eruptions.

Background:

Shiveluch has had over 60 large explosive eruptions during the past 10,000 years. Catastrophic eruptions took place in 1854 and 1956, when a large part of the lava dome collapsed and created a devastating debris avalanche.
It belongs to the Kliuchevskaya volcano group and is about 65,000 years old. Its summit is truncated by a broad 9-km-wide caldera of about 10,000 years of age, breached to the south. Many lava domes dot its outer flanks. Widespread tephra layers from Shiveluch's eruptions are valuable time markers for dating volcanic events in Kamchatka.
