Dezcabezado Grande is an andesitic to rhyodacitic stratovolcano with a 1,400 meter wide crater filled with ice; it is located in a volcanic field 20 km by 30, with Cerro Azul and Quizapu.

The last eruption of the Quizapu was Plinian, of VEI 3 , accompanied by an eruptive column more than 30 km high, and dated from June 1932 to 1933. It affected Valparaiso and the neighboring countries: Argentina, Brazil and Brazil. 'Uruguay.
