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 Central Volcanic Zone is one of four volcanic belts in the Andes; the others are the Northern Volcanic Zone, the Southern Volcanic Zone, and the Austral Volcanic Zone. [12] The Central Volcanic Zone is 1,500 kilometres (930 mi) long, [13] and 69 of its volcanoes have been active in the Holocene epoch. [13] Peruvian volcanoes include ...
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.
Nevados de Chillán is a group of stratovolcanoes located in the Andes of Ñuble Region, Central Chile, and is one of the most active volcanoes in the region.It consists of three overlapping peaks, 3,212 m (10,538 ft) Cerro Blanco (Volcán Nevado) at the northwest and 3,089 m (10,135 ft) Volcán Viejo (Volcán Chillán) at the southeast, with Volcán Nuevo in the middle.
Ollagüe is part of the Central Volcanic Zone (CVZ), [18] one of the volcanic arcs that exist in the Andes. The Andes have segments with volcanic activity and segments without; volcanic activity occurs only where the angle of subduction is relatively steep. There are four such segments, the Northern Volcanic Zone, the CVZ, the Southern Volcanic ...
Volcanism in South America occurs in four distinct zones along its western coast in the Andes: The Northern Volcanic Zone, the Central Volcanic Zone (CVZ), the Southern Volcanic Zone and the Austral Volcanic Zone. The volcanoes of Peru and the Central Andes belong to the CVZ, [36] which includes more than 50 [37] calderas, composite volcanoes ...
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 ...
Aucanquilcha is part of the Central Volcanic Zone (CVZ) of the Andes, a highly silicic volcanic zone in South America. The CVZ generates magmas at a rate of 0.11 cubic kilometres per millennium (0.026 cubic miles per millennium), one tenth of the global average of arc magma production, and lies about 135–180 kilometres (84–112 mi) above the Wadati–Benioff zone.
