Chachani

Chachani is a volcanic group in southern Peru, 22 kilometres (14 mi) northwest of the city of Arequipa. Part of the Central Volcanic Zone of the Andes, it is 6,057 metres (19,872 ft) above sea level. It consists of several lava domes and individual volcanoes such as Nocarane, along with lava shields such as the Airport Domes. Underneath Chachani lies a caldera. During the Pliocene and early Pleistocene, the volcanic group produced large ignimbrites such as the La Joya, Arequipa Airport, and Yura Tuff ignimbrites; afterwards, the volcanic group proper grew in the caldera until about 56,500 years ago. There have been no eruptions during historical times. Still, the volcano is considered to be only dormant, and due to its closeness to the city of Arequipa, it is considered high-risk.
