The Austral Volcanic Zone (AVZ) is a volcanic arc in the Andes of southwestern South America. It is one of the four volcanic zones of the Andes. The AVZ extends south of the Patagonian Volcanic Gap to Tierra del Fuego archipelago, a distance of well over 600 mi (1,000 km).
The Andes range has many active volcanoes distributed in four volcanic zones separated by areas of inactivity. The Andean volcanism is a result of the subduction of the Nazca Plate and Antarctic Plate underneath the South American Plate. The belt is subdivided into four main volcanic zones that are separated from each other by volcanic gaps.
Huaynaputina (/ ˌ w aɪ n ə p ʊ ˈ t iː n ə / WY-nə-puu-TEE-nə; Spanish: [wajnapuˈtina]) is a volcano in a volcanic high plateau in southern Peru.Lying in the Central Volcanic Zone of the Andes, it was formed by the subduction of the oceanic Nazca Plate under the continental South American Plate.
Coropuna is in the Central Volcanic Zone of the Andes, [13] [22] which contains 44 stratovolcanoes [23] – including many of the world's highest [22] – and several glaciated volcanoes. [24] Besides Coropuna, some of the latter are Sara Sara , Solimana , Mismi , Ampato , Hualca Hualca , Sabancaya , Chachani , Misti , Ubinas , Huaynaputina ...
There is an additional volcanic belt south of the Southern Volcanic Zone, the Austral Volcanic Zone, [7] associated with the subduction of the Antarctic Plate. [8] Sabancaya is located in the Central Volcanic Zone of the Andes, which extends through southern Peru. [9] Many volcanoes in the Central Volcanic Zone are poorly known, owing to their ...
Tuzgle is a prominent volcano of the back arc of the Andes and lies about 280 kilometres (170 mi) east of the main volcanic arc. Part of the Central Volcanic Zone of the Andes, its summit is 5,486 metres (17,999 ft) above sea level and it grew during different stages over a caldera and lava domes.
The country's National Geology and Mining Service lists 90 active volcanoes. [2] The volcanoes of the Andes originate from the subduction of the Nazca Plate under the South American Plate, while the volcanoes of Chile's Pacific islands formed from magma coming from three distinct hotspots, Easter, Juan Fernández and San Felix hotspots. The ...
Misti is a dormant volcano located in the Andes mountains in southern Peru, rising above Peru's second-largest city, Arequipa. It is a conical volcano with two nested summit craters, the inner one of which contains a volcanic plug or lava dome with active fumaroles. The summit of the volcano lies on the margin of the outer crater and is 5,822 ...
