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.
Between 14° S and 28° S lies one volcanic area with over fifty recently active systems, the Central Volcanic Zone (CVZ). Since the late Miocene between 21° S and 24° S a major ignimbrite province formed over 70 kilometres (43 mi) thick crust, the Altiplano–Puna volcanic complex, between the Atacama and the Altiplano.

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.
The Philippine archipelago is bounded by subduction zones which makes the region volcanically active. The most active volcano in the Philippines is the Mayon Volcano located in southeastern Luzon. [36] It is related to the subduction of Philippine Sea plate beneath the Philippine Mobile Belt. [4] Earthquakes (mag >6.0) in the Philippines (2019)
