Volcanoes and Glaciers Don’t Mix
Satellite Images of Klyuchevskaya Volcano
The 4,750-meter Klyuchevskaya is the highest and most active volcano on Kamchatka Peninsula, NE Russia.
Klyuchevskaya Volcano is still erupting. Natural-color satellite image by MODIS was acquired April 7, 2010. A plume of ash about 370 meters was reported above the crater summit. The dark tint seen on the lower slopes of the Shiveluch Volcano, located to the northeast of Klyuchevskaya, is ash deposits from an earlier eruption. Source: NASA/EO.
A plume towered above the summit of Klyuchevskaya Volcano on Russia’s Kamchatka Peninsula on February 13, 2010, when the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra satellite captured this false-color image. Directly over the summit, the plume is bright white, suggesting more steam than ash. The steep, cone-shaped volcano was shrouded in snow, and the rugged terrain was being illuminated from the south, which created dramatic shadows to the north and west. Both the mountain itself and the plume are casting a shadow (brown area) on the western and northern flanks of the volcano. Within this shadow, black rivulets of lava are visible on the northwest slopes. (Date: 13 February 2010). Image and caption: NASA
Klyuchevskaya’s most recent phase of eruptive activity began in January 2005. On February 21, the Kamchatkan Volcanic Eruption Response Team reported a lava flow down the northern flank of the volcano that melted a large portion of the Ehrman Glacier, the largest of several small glaciers capping the summit and flanks of the volcano.
