Two of Kamchatka’s active volcanoes appeared to be steaming in the autumn snowfall in mid-October, 2013. The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Aqua satellite flew over the region and captured this true-color image.

In the north, a broad light gray ash plume pours from Shiveluch, one of Kamchatka, Russia’s largest and most active volcanoes. According to Volcano Discovery website, there was increasing lava dome activity on the day this image was captured, with strong degassing and an ash plume which rose to 12,000 feet. A more violent eruption occurred on October 18, with explosions, avalanches and ash plumes rising to 20,000 to 23,000 feet.

To the south, a dark gray ash plume can be seen rising from the taller Kliuchevskoi volcano and blowing southward. A large red hotspot has been outlined in this image, indicating the locations where the thermal sensors on the MODIS instrument detected temperatures higher than background. In this case, the red hotspot likely marks fresh lava flow. The Kamchatka Volcanic Eruption Response Team (KVERT) reported multiple lava flows on the northwestern flank, with a new vent location between Kliuchevskoi and Kamen, which lies to the southeast.

Not to be outdone by Shiveluch, activity at Kliuchevskoi notched upward on October 18, with strong explosive and effusive activities. KVERT report ash emission reaching to about 30,000 feet, as well as lava fountains and heavy lava flow on the flank of the volcano.
