Mocho-Choshuenco

The compound Mocho-Choshuenco volcano is composed of two glacier-covered stratovolcanoes, located east of Lago Rinihué and SE of Lago Panguipulli and post-dating a 4-km-wide basaltic caldera. The small Choshuenco stratovolcano, 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 El Mocho volcano, constructed within the caldera, is postglacial and has reported eruptions from 1864 and 1937. Additional craters and basaltic scoria cones are located on the flanks of Mocho-Choshuenco, primarily on the NE and SW sides.
