This is a picture of the glow beneath the volcanic crust of the Tolbachik volcano in central Kamchatka, Russia. The massive eruption of Tolbachik began with little warning on Nov. 27, 2012, after 36 years of quiescence. Within two days of the eruption onset, the lava flows had already traveled nearly 10 km, covering an area of ~14 km2.
The eruption has formed a series of cinder cones that feed lava flows, which at the time of this writing extend for nearly 20 km over the barren slopes of the volcano down into snow-covered forests.Image credit: Pavel Izbekov, Geophysical Institute, University of Alaska Fairbanks
