Ash Cloud from Shiveluch Settles on Kamchatka
This page contains archived content and is no longer being updated. At the time of publication, it represented the best available science. However, more recent observations and studies may have rendered some content obsolete.
Since January 2005, several of the volcanoes on the Kamchatka Peninsula in northeastern Russia have been erupting off and on, with ash clouds, and pyroclastic and lava flows. This image shows a large plume of emissions streaming from the Shiveluch Volcano on March 7, 2005. Against the snow-covered terrain, the ash appears light brown, while the shadows cast by the plume are blue. The dark areas surrounding the base of the volcano to the southwest may be meltwater or mud flows caused by the eruption. To the south, a long plume is blowing westward from the Klyuchevskaya Volcano, as well.
Shiveluch has been producing many ash plumes throughout the first few months of 2005, and evidence of a recent eruption is scattered down the western flanks of the volcano and beyond in this image from March 10, 2005.
