Descabezado Grande ("the big decapitated") volcano in central Chile is an active stratovolocano with a 1.4 km wide ice-filled summit crater, a basal diameter of 11 km and a volume of 30 cubic km.
The only historical eruption was in 1932, when a lateral crater formed on the upper NNE, shortly after the end of the major 1932 eruption from nearby Quizapu volcano on the north flank of Cerro Azul. At the moment the volcano is dormant, but the NE corner of the caldera has active fumaroles.
