Kliuchevskoi Volcano-Russia

"Kliuchevskoi is one of the most active volcanoes of the Kamchatka Peninsula in Far Eastern Russia. The volcano has had more than 80 eruptions since 1697. On September 15, 1994, gas and ash shot out of the crater, creating a column 2 km high. Over the next two weeks the eruption continued, and on 1 October a giant eruption occurred. A cloud of ash rose 15-20 km above the volcano. A picture taken by a weather satellite showed that the ash cloud extended 565 km to the SE, and that it was moving at about 140 km/hr (~85 mile/hr)! While ash was being blown out the top of the volcano, new rivers of lava flowed down its flanks. During the next three days the eruption stopped, and only steam rose above the crater."
