Ash covers the western slopes of Karymsky Volcano in this natural-color satellite image (top). The image was collected on May 20, 2013, by the Operational Land Imager (OLI) on Landsat 8. Late-season snow remained on the surrounding Kamchatkan landscape. Karymsky was active throughout most of the Twentieth and early Twenty-first centuries. In early 2013 the volcano experienced regular small earthquakes related to the movement of magma, heat at the summit, and occasional ash falls.
