Coropuna 科罗普纳峰
Coropuna is a dormant volcano in the Cordillera Ampato segment of the Peruvian Andes; its summit reaches an altitude of 6,377 metres (20,922 feet) above sea level. The volcano, located 155 kilometres (96 miles) from Arequipa, is mostly made of lava flows on a basement formed by Miocene ignimbrites. Coropuna has been active for at least five million years, with the bulk of the current cone having formed during the Pliocene–Pleistocene.
