November 26, 2012 – CHILE – An eruption may have occurred at a remote volcano on the Chilean-Argentine border. There are some reports of a possible small plume drifting from Copahue volcano near the Chile-Argentina border. The volcano last erupted in 2000. Copahue is a stratovolcano nestled on the border between Argentina and Chile.
There are nine volcanic craters along a 2 km (1.2 mi) line, and the eastern summit crater contains a briny, acidic 300 m (1000 ft) wide crater lake. Twentieth-century eruptions from the crater lake have ejected pyroclastic rocks and chilled liquid sulfur fragments. –Earthquake Report, Wikipedia
