On 20 October, NASA's Landsat 8 captured multiple lava flows streamed down Klyuchevskaya northern and western flanks with its onboard Operational Land Imager (OLI). Klyuchevskaya (also spelled Kliuchevskoi), located on Russia's Kamchatka Peninsula, is one of the world’s most active volcanoes.
NASA reported: "Klyuchevskaya has been erupting since August 15, 2013, though the intensity of activity surged in October. The Kamchatka Volcanic Eruption Response Team (KVERT) reported a thick plume of ash and steam streaming from the summit on October 11. Subsequent days brought explosive eruptions, lava fountains, and volcanic tremors. At times, the ash plume rose from the summit (elevation 5 kilometers, or 16,000 feet) up to 7.5 to 10 kilometers (24,000 to 32,000 feet)."
