Klyuchevskoi, a volcano in Kamchatka, Russia's Far East, has become active in the past few hours, emitting clouds of ash reaching one kilometer above the crater, reported the local Seismological Station of the Kamchatka Experimental Seismological Party.
The crater was not seen to be blazing in the nighttime, which means there is no fresh lava inside it. Seismologists have noticed "spasmodic tremors," which indicated that more than 40 severe quakes were taking place 30 kilometers deep into the central crater.
The Klyuchevskoi is the highest active volcano in Asia and Europe, rising 4,835 meters above sea level. The last powerful eruptions from the top crater were registered between 1978 and 1993. Eruptions still continue today.
The volcano poses no threat to the town of Klyuchi, which is 30 kilometers away.
