Popis:

Shiveluch Volcano at Russia’s Kamchatka Peninsula on 25-02-2011, as recorded in false-color by Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra satellite. Remnants of a large pyroclastic flow is seen on its slopes. ASTER detected heat from the flow during or shortly after an event on 25-01-2011. Note how the heat signatures from January line up with the dark surface deposits visible on February 25; those deposits cover more than 10 square kilometers (4 square miles). Light brown ash covers the snow above the flow deposits, and a tiny plume rises from Shiveluch’s growing lava dome. Vegetation surrounding the volcano is colored dark red.
