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.
