A red glow indicating the presence of heat and a small plume of ash are evidence of the Klyuchevskaya (Kliuchevskoi) volcano's recent unrest. The volcano has been intermittently releasing bursts of steam, ash, and gas. The largest volcano on Russia's Kamchatkan peninsula, Klyuchevskaya is being watched carefully for signs of a more violent eruption.
Its neighboring volcano, Bezymianny, began to erupt on January 13, 2004. Though the eruption has subsided, a small plume of ash is still visible in this false-color image. The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on the Terra satellite captured this image on January 21, 2004.
Another image is also available showing a wider area around these volcanoes.
