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.
