Lava and Snow on Klyuchevskaya Volcano


acquired December 11, 2009
Dark lava streams down the southeast flank of Klyuchevskaya volcano in this satellite image. The dark gray lava—perhaps combined with deposits from lahars or pyroclastic flows—contrasts sharply with the volcano’s snow-covered and sunlit southern slopes, while a thin plume extends due west from the summit. According to the Smithsonian/U.S. Geological Survey Global Volcanism Program, Klyuchevskaya has been active throughout most of 2009.
