San Pedro volcano

stratovolcano 6145 m / 20,161 ft
Northern Chile, Bolivia and Argentina (South America), -21.88°S / -68.4°W
Current status: normal or dormant (1 out of 5)

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.
