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.
