Earth from Space 2001 Calendar

This image shows the area of the Kliuchevskoi volcano in Russia. The volcano is located on Kamchatka Peninsula in far eastern Russia, which is one of the most active volcano regions along the Pacific "Ring of Fire." Kliuchevskoi is the prominent white peak surrounded by red slopes toward the bottom of the image. Kliuchevskoi has erupted more than 80 times since 1697, most recently in autumn, 1994, when it produced a cloud of gas and ash that stretched more than 2 km (1.3 mi) high and more than 500 km (310 mi) to the southeast. The Kamchatka River runs horizontally across the image toward the top. The image was obtained by SIR-C/X-SAR on the Space Shuttle Endeavour on October 1, 1994 and shows an area about 30 km (19 mi) on a side.
