CoropunaCoropuna 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.
ChachaniChachani is a volcanic group in southern Peru, northwest of the city of Arequipa. Part of the Central Volcanic Zone of the Andes, it is above sea level. It consists of several lava domes and individual volcanoes such as Nocarane, along with lava shields such as the Airport Domes. Underneath Chachani lies a caldera. During the Pliocene and early Pleistocene, the volcanic group produced large ignimbrites such as the La Joya, Arequipa Airport and Yura Tuff ignimbrites; afterwards the volcanic group proper grew in the caldera until about 56,500 years ago.
HuaynaputinaHuaynaputina (ˌwaɪnəpʊˈtiːnə ; wajnapuˈtina) is a volcano in a volcanic high plateau in southern Peru. Lying in the Central Volcanic Zone of the Andes, it was formed by the subduction of the oceanic Nazca Plate under the continental South American Plate. Huaynaputina is a large volcanic crater, lacking an identifiable mountain profile, with an outer stratovolcano and three younger volcanic vents within an amphitheatre-shaped structure that is either a former caldera or a remnant of glacial erosion.
SabancayaSabancaya is an active stratovolcano in the Andes of southern Peru, about 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. The Central Volcanic Zone includes a number of volcanoes, some of which like Huaynaputina have had large eruptions and others such as Sabancaya and Ubinas have been active in historical time. Sabancaya forms a volcanic complex together with Hualca Hualca to the north and Ampato to the south and has erupted andesite and dacite.
TutupacaTutupaca is a volcano in the region of Tacna in Peru. It is part of the Peruvian segment of the Central Volcanic Zone, one of several volcanic belts in the Andes. Tutupaca consists of three overlapping volcanoes formed by lava flows and lava domes made out of andesite and dacite, which grew on top of older volcanic rocks. The highest of these is usually reported to be tall and was glaciated in the past. Several volcanoes in Peru have been active in recent times, including Tutupaca.
UbinasUbinas is an active stratovolcano in the Moquegua Region of southern Peru, approximately east of the city of Arequipa. Part of the Central Volcanic Zone of the Andes, it rises above sea level. The volcano's summit is cut by a and caldera, which itself contains a smaller crater. Below the summit, Ubinas has the shape of an upwards-steepening cone with a prominent notch on the southern side. The gently sloping lower part of the volcano is also known as Ubinas I and the steeper upper part as Ubinas II; they represent different stages in the volcano's geological history.
TicsaniTicsani is a volcano in Peru northwest of Moquegua and consists of two volcanoes ("Old Ticsani" and "Modern Ticsani") that form a complex. "Old Ticsani" is a compound volcano that underwent a large collapse in the past and shed of mass down the Rio Tambo valley. Today an arcuate ridge remains of this edifice. "Modern Ticsani" is a complex of three lava domes which were emplaced during the Holocene. Two large eruptions took place during the Holocene, producing the so-called "Grey Ticsani" and "Brown Ticsani" deposits; the last eruption occurred after the 1600 eruption of neighbouring Huaynaputina.
Andagua volcanic fieldThe Andagua volcanic field (also known as Andahua) is a volcanic field in southern Peru which includes a number of cinder cones, lava domes and lava flows which have filled the Andagua Valley (which is also known as Valley of the Volcanoes for this reason). The volcanic field is part of a larger volcanic province that clusters around the Colca River and is mostly of Pleistocene age, although the Andagua sector also features volcanic cones with historical activity, with the last eruption about 370 years ago.
ArequipaArequipa (aɾeˈkipa; Aymara and Ariqipa) is a city in Peru and the capital of the eponymous province and department. It is the seat of the Constitutional Court of Peru and often dubbed the "legal capital of Peru". It is the second most populated city in Peru, after Lima, with an urban population of 1,296,278 inhabitants according to the 2017 national census. Its metropolitan area integrates twenty-one districts, including the foundational central area, which it is the seat of the city government.
