Global Volcanism Program | Image GVP-03880

A group of volcanologists are standing on the surface of a debris avalanche deposit produced by collapse of the Cerro Quemado NE flank about 1,150 years ago, with the avalanche scarp in the background to the SW. The scarp, which fills all but the far right-hand slope of this view, is 1 x 1.5 km wide. An associated lateral blast also swept across a 40 km2 area to the NE. The eruption concluded with the emplacement of a small lava dome near the headwall of the scarp. Photo by Lee Siebert, 1993 (Smithsonian Institution).
