The late-Pleistocene to Holocene Quetrupillan stratovolcano is at the center of a group of three volcanoes trending transverse to the Andean chain. Constructed within a large 7 x 10 km wide caldera, 2360-m-high, glacier-covered Quetrupillan contains a 3.5-km-wide caldera and has more silicic lavas than its more prominent neighbors Villarrica and Lanín. The basaltic scoria cone Huililco lies 12 km NE of Quetrupillan, a rhyolitic lava dome lies on the south flank of the caldera, and the Volcanes de Reyehueico produced basaltic-andesite lava flows 15 km south of the summit caldera. Some of the most recent activity produced the Volcanes de Llancahue pyroclastic cones near the SW margin of the older caldera. Petit-Breuilh (1994 pers. comm.) reported a single historical eruption from Quetrupillan in 1872.
