An aerial view from the NW overlooks Planchón-Peteroa, a complex volcano with several overlapping calderas. In the left foreground is the caldera wall of Planchón volcano. The crater complex of Peteroa is in the center, and Volcán Azufre lies at the upper right. Activity began in the Pleistocene at Volcán Azufre, followed by formation of Volcán Planchón, 6 km to the north. Volcán Peteroa has been active into historical time and contains a small steaming crater lake.

地質学的概要

Planchón-Peteroa is an elongated complex volcano along the Chile-Argentina border with several overlapping calderas. Activity began in the Pleistocene with construction of the basaltic andesite to dacitic Volcán Azufre, followed by formation of the basaltic and basaltic andesite Volcán Planchón, 6 km N. About 11,500 years ago much of Azufre and part of Planchón collapsed, forming the massive Río Teno debris avalanche, which traveled 95 km to reach Chile's Central Valley. Subsequently, Volcán Planchón II was formed. The youngest volcano, andesitic and basaltic andesite Volcán Peteroa, consists of scattered vents between Azufre and Planchón, and and contains a small steaming crater lake. Reported eruptions from the complex have been dominantly explosive, although lava flows were emplaced in 1837 and 1937.
