Casiri volcanic complex
|Elevation||5,650 m (18,540 ft)|
|Location||Peru, Tacna Region|
|Parent range||Andes, Barroso|
|Age of rock||Unknown|
|Volcanic arc/belt||Central Volcanic Zone|
Casiri (possibly from Aymara for bawler) is a mountainous complex in the Barroso mountain range in the Andes of Peru, about 5,650 metres (18,537 ft) high. It is located at the border of the Tacna Region, Tacna Province, Palca District and the Tarata Province, Tarata District.
Casiri is part of the Central Volcanic Zone, one of the four volcanic belts in the Andes. Volcanoes in this belt are often high but also poorly known and studied owing to their remote location; the eruption of Huaynaputina in 1600 was observed from Arequipa and is thus better documented.
The volcano has a height of 1,050 metres (3,440 ft), a diameter of 5 kilometres (3.1 mi) and a volume of 7 cubic kilometres (1.7 cu mi). Four centres are aligned on an east-west trending ridge, presumably formed through a shift in the conduit, with the youngest centre southeast of the ridge. This youngest centre has a summit crater, a western lava dome of possibly dacitic composition and two southbound lava flows showing signs of having been active after the ice ages. A sulfur mine Gloria is associated with the lava flows, and another is found on the northwest side of the volcano. There are no reports of historical activity. This volcano does not appear to be a threat.
Off the western coast of South America, the Nazca Plate subducts beneath the South America Plate in the Peru-Chile Trench. This process is responsible for volcanism in the Andes, which occurs in three volcanic belts, the Northern Volcanic Zone, the Central Volcanic Zone and the Southern Volcanic Zone.
