A plume rises from the summit crater of Nevado del Ruiz volcano on 10 December 1985. Pyroclastic surge and ashfall deposits from the 13 November eruption coat the glaciers. Glaciers on the upper NE-flank headwall of the Azufrado valley (foreground) were scoured by pyroclastic surges. Photo by Tom Pierson, 1985 (U.S. Geological Survey).
