Mocho-Choshuenco volcano

Mocho-Choshuenco volcano east of Lago Rinihué and SE of Lago Panguipulli in central Chile is a twin volcano composed by 2 glaciated stratovolcanoes. The younger of them, El Mocho, has been active in historic times, in 1864 and in 1937.

Background:

The 2 volcanoes are built above a 4 km wide basaltic caldera: The small 2415-m-high Choshuenco stratovolcano was built was constructed on the NW rim of the caldera, is late-glacial in age. A major plinian eruption produced the Neltume Pumice about 10,300 years ago.
The larger andesitic-to-dacitic, 2422-m-high El Mocho volcano is located in the caldera and has been historically active. Flank cones are located on the flanks of Mocho-Choshuenco, primarily on the NE and SW sides.
