The Kamchatka experimental seismological party reported that a large number of surface earthquakes 0.5 km under the volcano have occurred in the past day. The ash has reached a height of 4,000 meters above the crater. A thick ash trail has extended 20 km to the southeast.
The Shiveluch volcano is one of the largest, 3,283 meters above sea level, and northernmost active volcanoes in Kamchatka.
This is one of the largest eruptions to occur in Shiveluch in 100-300 years. The last were noted in 1854 and 1964. Weak and moderate eruptions occur considerably more frequently.
The current activity began on January 11 after a period of inactivity.
Klyuchevskaya, the largest volcano in Eurasia (4,833) is also erupting.
