Planchón-Peteroa is a complex volcano extending in a north-south direction along the border between Argentina and Chile. It consists of volcanoes of various ages with several overlapping calderas. Those include Volcán Planchón, Volcán Peteroa and Volcán Azufre.
A partial collapse of the complex about 11,500 years ago produced a major debris avalanche, which followed the course of the Teno River until reaching the Chile Central Valley.
Peteroa has a crater lake. Lagunas de Teno lies at the foot of Planchón volcano. In this area also is the Vergara International Pass.
[edit] September 6, 2010 eruption
Planchón-Peteroa Volcano erupted on September 6th followed by a stronger eruption on September 18th. On September 21st, the volcano erupted once again emitting a dark gray plume of ash. Planchón-Peteroa is located on the border between Chile and Argentina, as volcanic ash is being blown southeast into Argentina. Residents of Argentina were warned by authorities to evacuate before Planchón-Peteroa would erupt again.
