Calbuco

Stratovolkan · Chile · 1974 m

Calbuco is one of the most active volcanoes of the southern Chilean Andes. The isolated volcano rises to 2003 m south of Lake Llanquihue, which is visible at the upper right. The summit ridge (center) of the volcano is the remnant of an older volcano that collapsed during the late Pleistocene and produced a 3 cu km debris avalanche that reached the lake. Subsequent eruptions generated andesitic lava flows, breccias, and tuffs that filled the scarp and were subsequently topped by an historical lava-dome complex (right center).

Ringkasan geologi

Calbuco is one of the most active volcanoes of the southern Chilean Andes, along with its neighbor, Osorno. The late-Pleistocene to Holocene andesitic volcano is immediately SE of Lake Llanquihué in the Chilean lake district. 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.). The edifice is elongated in a SW-NE direction and is capped by 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 one of the largest historical eruptions in southern Chile took place from Calbuco in 1893-1894 that concluded with lava dome emplacement. Subsequent eruptions have enlarged the lava-dome complex in the summit crater.
