In this incredible capture taken on 30 September 1994, we see a major eruption of Klyuchevskaya Sopka as seen by the astronauts aboard the Space Shuttle Endeavour (mission: STS-68). The eruption cloud reached 60,000 feet above sea level and the winds carried ash as far as 640 miles (1,030 km) southeast from the volcano into the North Pacific air routes. This picture was made with a large format Linhof camera. While astronauts used handheld camera’s to keep up with the Kamchatka event, instruments in the cargo bay of Endeavour recorded data to support the Space Radar Laboratory (SRL-2) mission.

Klyuchevskaya Sopka is a stratovolcano, the highest mountain on the Kamchatka Peninsula of Russia and the highest active volcano of Eurasia. Its steep, symmetrical cone towers about 100 kilometres (60 mi) from the Bering Sea. The volcano is part of the natural Volcanoes of Kamchatka UNESCO World Heritage Site. Klyuchevskaya’s first recorded eruption occurred in 1697 and it has been almost continuously active ever since. [source]
