Karymsky is one of the many active volcanoes on Russia’s Kamchatka Penninsula. On the afternoon of October 8, 2010, it sent a plume of gas and ash 2,700 meters (9,000 feet) high and about 90 kilometers (50 miles) downwind over the Kronotskiy Kroniv (Kronotsky Gulf). This natural-color satellite image was acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard Aqua. The region’s white, snow-covered peaks stand out against the land surface, colored in the hues of autumn. The light gray volcanic plume extends almost directly east from the volcano’s summit.
