The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on the Terra satellite captured this false color image of the Kamchatka Peninsula, in far eastern Russia, on January 21, 2004. Plumes of ash and the glowing red colors, indicating the presence of heat, give evidence to recent volcanic activity on Klyuchevskaya (Kliuchevskoi), at top, and neighboring Bezymianny (bottom). These two volcanoes have been intermittently releasing bursts of steam, ash, and gas. Klyuchevskaya ( 4,750 m or 15,584 ft) is the largest volcano on Russia’s Kamchatkan Peninsula and is being monitored carefully for signs of a more violent eruption. Notice the long, triangular shadow of the mountain between the two volcanoes -- a hint that this image was taken during the morning hours when the Sun was in the southeastern sky.
