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.

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

Quetrupillan stratovolcano is seen in this NASA International Space Station image with north to the upper right. The volcano was constructed within a large 7 x 10 km wide caldera. The 2360-m-high Quetrupillan volcano has produced more silicic lavas than its more prominent neighbors Villarrica and Lanín. Clusters of monogenetic vents, including lava domes and pyroclastic cones, are found on the southern side of the volcano.

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.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
