Tolbachik Volcano, Kamchatka, Russia

Seismic activity has declined but the eruption continues at Tolbachik volcano, Kamchatka. During the peak activity on 28-29 November 2012 the fissures spread over tens of kilometres, and the eruption was heard 60 kilometres away. The current eruption is similar to the Great Fissure eruption in 1975-76, but lower in intensity. A fissure 5 kilometres long has formed on the southern slope of the Plosky Tolbachik, in the same area as 36 years ago, but at a higher elevation about two thousand metres above sea level. There are two active centres which are producing lava flows. A 10 kilometre long lava flow destroyed a monitoring station of the Institute of Volcanology and Seismology on Vodopadny creek, as well as the Leningradskaya station of the institute. A base of the Volcanoes of Kamchatka natural park has also been destroyed in the same area. Ashfall was reported 65 kilometres from the volcano up to a depth of 4 cm. Eruptions at the upper fissure have stopped, but the lower fissure continues to be active. Tolbachik volcano is 343 kilometres south west of Petropavlovsk-Kamchatsky.
