The eruption of the volcano in Kamchatka Flat Tolbachik changed topography of the surrounding area, according to Klyuchevskaya volcano.
Flat Tolbachik began erupting on 27 November. In the area of the southern slope formed two fractured breakthrough emission of lava. The lava flow from the top break was more than six kilometers from the bottom — 18 kilometers. Periodically over Tolbachik ash column rises.
On the eve of the group of Volcanology and Seismology made Aerial circled Tolbachik fissure eruption. Concurrent thermal shooting lava flows.
During the flyby, seismologists have established a mobile seismic station, and within an hour were recorded seismic events associated with explosions in the crater side breaks. Geologists selected samples of fresh lava and ash for chemical analysis.
The last eruption of the volcano Tolbachik called Great Tolbachik Fissure eruption occurred in 1976 and was the first in the history of Russian science, predicted with complete accuracy. The eruption changed the topography of the surrounding area was the cause of a local ecological disaster, which killed all living at a distance of tens of kilometers from the volcano.
Tolbachik consists of two volcanoes — Flat Tolbachik (3.085 thousand meters altitude) and acute Tolbachik (3.682 thousand meters). The nearest town — City Keys — removed from the foot of the volcano 60 kilometers.
