Mocho-Choshuenco Volcano is located in central Chile. The volcano contains parasitic craters and scoria cones on the NE and SW flanks.

Mocho-Choshuenco Volcanic Complex is considered one of the most hazardous volcanoes in Chile's Southern Volcanic Zone.

In the past 18,000 years Mocho-Choshuenco has experienced three large (volume = 1 km3) Plinian eruptions (Neltume, Pirehueico and Huilo) and a large pyroclastic density current and associated sub-Plinian event (Enco).

Based on geological surveys, an explosive eruption has occurred every ~ 220 years with the youngest, confirmed eruption from Mocho-Choshuenco in 1864.
