On Sunday morning, February 17, 2008, the skies above Shiveluch Volcano in Russia's Far East were clear and calm. When the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA's Terra satellite passed overhead, it caught this view of a column of ash from a recent eruption seemingly frozen in the air over the mountain. The southern slopes of the snow-covered volcano were brown with ash. The top image in this pair shows a close-up view of the ash column, which rises over the volcano to the east (right) of the active caldera. The bottom image shows the entire volcano. In this view, the shadow of the ash column looms over the northern flank of the volcano.The bowl-shaped, shadow-filled feature to the left of the ash column is the crater, or caldera, of Young Shiveluch, where most eruptive activity takes place today. Shiveluch is the northernmost of the active volcanoes on the Kamchatka Peninsula.
