Volcán Copahue is a composite volcano constructed along the Chile-Argentina border within an 8-km-wide Pleistocene caldera. The eastern summit crater, part of a 2-km-long, ENE-WSW line of nine craters, contains the briny El Agrio crater lake and displays intense fumarolic activity. Infrequent explosive eruptions have been recorded since the 18th century from the 2965-m-high volcano.
