San Pedro Volcano is located in the Atacama desert of northern Chile. It is one of the highest active volcanoes in the world.

The volcano has two peaks. San Pedro is the western summit and San Pablo (6092 m) is in the east. A large debris avalanche is visible on the western slope of San Pedro, which is similar to the eruption of Mt St Helens. A younger scoria cone (La Poruña) built within the crater. The cone was the source of an 8-km-long lava flow.

Three Quaternary composite cones, San Pedro, Tolimán, and Atitlán, are found
along the south side of the Lake Atitlán in the Guatemalan Highlands.

A well preserved cinder cone is located 10 km west of the volcano at an elevation of 3500 m.
