Planchón-Peteroa, Complex volcano at Argentina-Chile border
Planchón-Peteroa extends north to south along the border, reaching an elevation of 4,107 meters with multiple overlapping calderas and a crater lake.
A substantial debris avalanche occurred 11,500 years ago, traveling through the Teno River and reaching the Chile Central Valley.
Scientists from Argentina and Chile conduct regular research at the volcano to monitor seismic activities and understand volcanic patterns.
Visitors need special permits and mountaineering equipment to access the volcanic area due to high altitude conditions and remote location.
The volcanic complex includes three distinct formations: Volcán Planchón, Volcán Peteroa, and Volcán Azufre, each with specific geological characteristics.
