A series of ash spews has been registered from the crater of the Shiveluch volcano on Russia's Kamchatka Peninsula.

One of the spews reached an altitude of 10 kilometres above the summit, the Kamchatka branch of the Geophysical Service of the Russian Academy of Sciences (RAN) told Itar-Tass on Tuesday.

A plume of ash 61 by 35 kilometres in size moved 24 kilometres northeast of the volcano. Increased seismic activity is observed on the volcano. The giant mount presents no danger for nearby settlements, believe scientists that have been without interruption monitoring the eruption.

However, ash clouds spewed by Shiveluch may be dangerous for local aviation. It is also not safe to approach the volcano during eruption, specialists say.

Shiveluch became active on December 5 after a relatively calm period since autumn 2005. This volcano is regarded as one of the most active on Kamchatka. Its height is 3,283 metres above sea level. The volcano eruptions are explosive, which makes it difficult to forecast them.

The Volcano eruptions in 1864 and 1964 were classified by scientists as catastrophic. The nearest settlement Klyuchi is located at a distance of some 50 kilometres from Shiveluch.
