Chusmiza complex (also known as Cerros de Sotoca)[1] is a Miocene volcano in Chile. It is the largest stratovolcano of the Miocene epoch in the western Andean escarpment, with a volume of 400 cubic kilometres (96 cu mi). It is constructed from andesite.[2] Potassium-argon dating has established an age of 11.3±0.3 mya.[1]
