The eruption was accompanied by an earthquake on the volcano that lasted for about 10 minutes, said the Seismology and Volcanology laboratory of the Kamchatka branch of the Russian Geophysical Service, reported Itar-Tass.
The gas and ash plume was drifting to the south but there was no ash fall registered at the settlement of Klyucho some 50km from the foot of the volcano.
