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 ...
Cotopaxi is among the highest active volcanoes in the world. Cotopaxi is known to have erupted 87 times, resulting in the creation of numerous valleys formed by lahars (mudflows) around the volcano. [2] An ongoing eruption began on 21 October 2022. [3]
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 ...
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.
San Pedro is a Holocene composite volcano in northern Chile and at 6,155 metres (20,194 ft) in elevation one of the highest active volcanoes in the world. Part of the Chilean Andes' volcanic segment, it is part of the Central Volcanic Zone of the Andes, one of the four tracts of the Andean Volcanic Belt.
Lascar is a stratovolcano in Chile within the Central Volcanic Zone of the Andes, a volcanic arc that spans Peru, Bolivia, Argentina and Chile. It is the most active volcano in the region, with records of eruptions going back to 1848. It is composed of two separate cones with several summit craters.
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.
Sabancaya is an active stratovolcano in the Andes of southern Peru, about 70 kilometres (43 mi) northwest of Arequipa.It is considered part of the Central Volcanic Zone of the Andes, one of the three distinct volcanic belts of the Andes.
