ISS014-E-17165 (21 March 2007) --- A plume at Shiveluch Volcano, Kamchatka Peninsula, Russia is featured in this image photographed by an Expedition 14 crewmember on the International Space Station. Shiveluch, one of Kamchatka's most active volcanoes, began its latest activity with gas and steam emissions in mid-late March 2007. This image was captured around mid-morning on or around March 21 2007, and shows a steam plume, probably containing minor amounts of ash, blowing westward from the summit of the volcano. The crewmembers were transiting the southern tip of Russia's Kamchatka Peninsula; with a clear view of the volcano about 5 degrees north of the ground track of the station. Subsequent eruptions on March 29 and 30 have been recorded by the Kamchatka Volcano Observatory and NASA. The volcano's southern flank, clearly visible in this northeast-looking oblique view, comprises a horseshoe-shaped caldera from a late Pleistocene eruption, subsequently blanketed by additional ash deposits, and highlighted by the snow cover. The peak of Shiveluch is a distinctive brown color due to the removal of snow, exposure of rock forming the summit, and deposits of new ash. The relatively smooth landscape of the south contrasts with the large, steep valleys on the northern slope of the volcano. Low clouds wrap around the eastern part of the mountain, obscuring the lower elevations.
