Calbuco
About Calbuco
Calbuco is a very active late Pleistocene to Holocene andesitic volcano in the southern Chilean Andes immediately SE of Lake Llanquihué in the Chilean lake district. The edifice is elongated in a SW-NE direction and has a 400-500 m wide summit crater. The complex evolution included collapse of an intermediate edifice during the late Pleistocene that produced a 3-km3 debris avalanche that reached the lake. It has erupted frequently during the Holocene, and a major eruption in 1893-1894 concluded with lava dome emplacement. Subsequent eruptions have enlarged the lava-dome complex in the summit crater. Guanahuca, Guenauca, Huanauca, and Huanaque, all listed as synonyms of Calbuco (Catalog of Active Volcanoes of the World), are actually synonyms of nearby Osorno volcano (Moreno 1985, pers. comm.).
