San Pedro volcano in the Atacama desert of northern Chile is one of the highest active volcanoes in the world.
San Pedro volcano is a twin volcano with 2 peaks, San Pedro (the western summit) and the older sister volcano San Pablo (6092 m) in the east.

A large debris avalanche, similar to the one at Mt St Helend in 1980, occurred at San Pedro in the past, and the present-day cone grew within the depression. The debris avalanche deposit is visible on the western lower slopes of San Pedro.
Thick dacitic lava flows with steep-sided fronts cover the upper slopes of San Pedro's cone which has a crater. There is a young-looking scoria cone on the western flank (La Poruña), which erupted an 8 km-long lava flow about 103,000 years ago.
Reports of varying degrees of reliability have recorded a number of eruptions in the past centuries.

Note: a volcano with the same name is at Lake Atitlán in the Guatemalan Highlands, forming the prominent group of San Pedro, Tolimán, and Atitlán volcanoes.
