On October 28, 2010 Shiveluch Volcano erupted, sending an ash plume 25,000 feet (7,600) meters high. Despite moderate cloud cover, the ash was visible from space. This natural-color satellite image shows the light brown plume rising from Shiveluch and out over the Kamchatkan coast and Kamchatskiy Zaliv (Gulf of Kamchatka). Beneath the ash and clouds snow covers most of the land. To the south of Shiveluch a smaller, darker plume is visible over Klyuchevskaya, another of the currently active Kamchatkan volcanoes.
