Paniri

Paniri (Aymara) is a stratovolcano located in El Loa Province, Antofagasta Region, Chile, and near the border with Bolivia. To its northwest lie the twin volcanoes San Pedro and San Pablo, and to its southeast lies Cerro del León, from which it is separated by the huge Chao lava dome.

The volcano features lava flows, which are well preserved on the south-southwest flanks, and both a crater and a scoria cone on its summit. Paniri also shows evidence of glacier activity on its southeastern slope. The volcano developed in four stages, the last two of which generated the main cone. One date obtained from the youngest stage is 400,000 years ago, with an uncertainty of 50,000 years.

Claudio Lucero and Nelson Muñoz made the first recorded ascent of Paniri in 1972. They found archaeological remains on its summit. The mountain is the sacred mountain for the village of Ayquina.

Paniri is part of the San Pedro-Linzor volcanic chain, a chain of volcanoes formed by lava flows and pyroclastic flows. Composition of the rocks ranges from basaltic andesite and dacite.
