Shadow Cast by Bezymianny Volcano

Shadow Cast by Bezymianny Volcano

Despite no reports of activity, Bezymianny Volcano exhibited a modest plume on November 25, 2009. The plume appears translucent white in this false-color satellite image acquired by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) aboard NASA’s Terra spacecraft. The white color and absence of visible ash on the snow-covered peak suggest that the plume is mostly steam. A striking shadow cast by the plume darkens the southern flank of neighboring Kamen Volcano. Bezymianny and Kamen are two of many volcanoes located on Russia’s Kamchatka Peninsula.
