Firura
Firura is an extinct volcano of the Central Andean Volcanic Belt, located in the Arequipa Region of southern Peru. Together with Sara Sara, Solimana (volcano), 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 . Lava flows and stratovolcanoes form a long field. Aside from the main summit Firura, there also are Soncco Orcco (), Jahsaya () and separating Firura from Solimana Antapuna (). 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. Much of the southern side of the volcano above alt ...

Arequipa Region
Arequipa ( ay, Ariqipa; qu, Ariqipa) is a department and region in southwestern Peru. It is the sixth largest department in Peru, after Puno, Cuzco, Madre de Dios, Ucayali, and Loreto, its sixth most populous department, and its eleventh least densely populated department. It is bordered by the departments of Ica, Ayacucho, Apurímac and Cusco in the north, the Department of Puno in the east, the Department of Moquegua in the south, and the Pacific Ocean in the west. Its capital, also called Arequipa, is Peru's second-largest city. Geography This department has a rough topography, which is characterised by heavy layers of volcanic lava covering large areas of its inter-Andean sector. It has deep canyons such as the ones formed by the Ocoña and Majes rivers. Plateaus range in height from medium, such as La Joya, and high-altitude ones such the Arrieros Pampa and those located in the zones of Chivay, Huambo and Pichucolla. Volcanic cones, such as Misti, Chachani, Ampato, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coropuna
Coropuna is a dormant compound volcano located in the Andes mountains of southeast-central Peru. The upper reaches of Coropuna consist of several perennially snowbound conical summits, lending it the name Nevado Coropuna in Spanish. The complex extends over an area of and its highest summit reaches an altitude of above sea level. This makes the Coropuna complex the third-highest of Peru. Its thick ice cap is the most extensive in Earth's tropical zone, with several outlet glaciers stretching out to lower altitudes. Below an elevation of , there are various vegetation belts which include trees, peat bogs, grasses and also agricultural areas and pastures. The Coropuna complex consists of several stratovolcanos. These are composed chiefly of ignimbrites and lava flows on a basement formed by Middle Miocene ignimbrites and lava flows. The Coropuna complex has been active for at least five million years, with the bulk of the current cone having been formed during the Quat ...

Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...
