Quetrupillan stratovolcano (left) lies at the center of a group of three volcanoes trending transverse to the Andean chain. It is seen here from the summit of Villarrica volcano (at the western end of the chain), with conical Lanín volcano at the eastern end in the background. The 2360-m-high Quetrupillan volcano was constructed within a large 7 x 10 km wide caldera; a smaller caldera truncates the summit. Some of the most recent activity produced pyroclastic cones along the right-hand flank, near the SW margin of the older caldera.
