Planchón-Peteroa volcano eruptions

complex volcano 4107 m / 13,474 ft
Central Chile and Argentina, South America, -35.24°S / -70.57°W
Eruption list: 2018, 2010-2011, 1998, 1991, 1967, 1962, 1960, 1959, 1938, 1937, 1889-94 (?), 1878, 1872 (?), 1869 (?), 1860, 1842 (?), 1837, 1835, 1762, 1660


2010 eruption
Continuous strong ash eruptions from Planchón-Peteroa volcano produced an ash plume reaching 25,000 ft (8 km) altitude on 13 January 2010.

2001 intense fumarolic activity
Intense, increased fumarolic activity occurred at Planchón-Peteroa volcano in Jan-Feb 2001.

1998 ash eruption
In November 1998 small phreatic eruptions occurred at the volcano. Ash fell on Carrizales town, 8 km to the NW.

1991 eruption - ash emission and contamination of water
On 9 February 1991 an explosive eruption occurred at Planchon-Peteroa volcano, producing an ash plume of 1000 m height, and causing ash fall in 30 km distance ESE from the volcano.
Large numbers of fish were killed in the Claro and Teno rivers, and the water supply for Los Queñes (population ~1,200), 35 km NW of the volcano, was contaminated. It is thought that this happened because during the initial phase of the eruption, water was ejected from the crater lake and entered the the Claro and Teno rivers.

1937 eruption
