The different volcanic zones are intercalated by volcanic gaps, zones that, despite lying at the right distance from an oceanic trench, lack volcanic activity. [13] The Andes has three major volcanic gaps the Peruvian flat-slab segment (3 °S–15 °S), the Pampean flat-slab segment (27 °S–33 °S) and the Patagonian Volcanic Gap (46 °S–49 ...
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.
The Andes mountain chain originated from the subduction of the Nazca Plate below the South American Plate and was accompanied by extensive volcanism. Between 14° S and 28° S lies one volcanic area with over fifty recently active systems, the Central Volcanic Zone (CVZ).
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.
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 ...
Part of the Chilean Andes' volcanic segment, it is considered a member of the Southern Volcanic Zone (SVZ), one of the three distinct volcanic belts of South America. This most active section of the Andes runs along central Chile's western edge, and includes more than 70 of Chile's stratovolcanoes and volcanic fields. Calabozos lies in an ...
Part of the Central Volcanic Zone of the Andes, its highest summit is 5,868 metres (19,252 ft) above sea level and features a summit crater that opens to the south. The western rim of the summit crater is formed by a compound of lava domes , the youngest of which features a vigorous fumarole that is visible from afar.
Volcán Putana, sometimes referred to as Jorqencal or Machuca, is a stratovolcano located In the Central Volcanic Zone (CVZ) of the Andes on the border between Bolivia and Chile and close to the Sairecabur volcanic complex. Its summit is 5,884 metres (19,304 ft) above sea level and contains a summit crater with two smaller craters nested within it.
