Two eruptions preceded it yesterday, both to a 2 kilometre height. Aerospace photographs show vivid traces of thermal anomalies.
Kamchatka's northernmost volcano, 3,283 m high, Shiveluch awoke, January 11, after a long quiet time. It is not dangerous to settlements, though landslides threaten local roads, and have damaged a highway from Kluchi to Ust-Kamchatsk on several recent occasions.
Shiveluch has disastrous eruptions every hundred to 300 years. The latest were in 1854 and 1964. Small and medium-scale eruptions are far more frequent.
