Шаблон:Infobox mountain Firura is an extinct volcano of the Central Andean Volcanic Belt, located in the Arequipa Region of southern Peru. Together with Sara Sara, Solimana and Coropuna it forms one of the Central Andean volcanoes. It is in the Andes, north of the Pucuncho Basin.

Description

Two domes form the Firura volcano, which has a low relief of Шаблон:Convert. Lava flows and stratovolcanoes form a Шаблон:Convert long field. Aside from the main summit Firura, there also are Soncco Orcco (Шаблон:Convert), Jahsaya (Шаблон:Convert) and separating Firura from Solimana Antapuna (Шаблон:Convert). The complex has generated basaltic or basaltic andesite lava flows that reach down into inhabited areas, as well as an ignimbrite resulting from the collapse of the ancient crater. A collapse of the crater was also responsible for the formation of a landslide dam in the Cotahuasi River valley. The date of the last volcanic activity is Pleistocene to Holocene, but it does not appear to be a significant hazard and is classified as a low-risk volcano.

Much of the southern side of the volcano above Шаблон:Convert altitude is covered with perennial snow. A small glacier (>Шаблон:Convert) is found on the southern summit of Firura and reaches down to Шаблон:Convert. This glacier appears to be located above the local equilibrium line altitude.

Firura has well preserved moraine systems. A major moraine system with a relief of Шаблон:Convert was left by the Last Glacial Maximum, although expansion of glaciers on the northern flank was constrained on a high plateau. The prevalent aridity of the climate impedes the degradation of these moraines.
