The Inca sites are the highest ones, though some occur next to bogs such as the one next to the village Maucta Llacta. [22] Beginning in the mid-Pliocene, the Coropuna I and Coropuna II volcanoes were constructed by large lava flows. In this study, 258 Landsat images were used to calculate snow cover from 1988–2013 on El Nevado Coropuna volcano, home of a tropical glacier.

Lua error in Module:Coordinates at line 668: callParserFunction: function "#coordinates" was not found. This means that ice on Coropuna will not completely disappear in the coming decades as some have feared. Evidence has been found of a later minor expansion 6,000 years ago.
Coropuna is a dormant[4] volcano in the southern Peruvian Andes and belonging to the Central Volcanic Zone; its summit reaches an altitude of 6,377 metres (20,922 feet) above sea level.
The magmas originated at a depth of 8–12 kilometres (5.0–7.5 mi).
[53] Much of the surface loss happened in the 1980s and 1990s. [42] A 2010 study showed the average thickness was 80.8 ± 16.5 metres (265 ± 54 ft), with a total volume of 4.62 ± 0.94 cubic kilometres (1.11 ± 0.23 cu mi). The Landsat archive provides a temporally extensive data set to study glaciers around the world. We did not experience any difficulties combining SPOT and Landsat data. Image taken from a commercial airliner on Dec. 22, 2014 showing the south side of Nevado Coropuna. No fresh snow is present in the image, although the wet season began just days later. Co-authors: [64] These events were also accompanied by lower cloud cover, higher temperatures, and lower wind speed, increasing the glacier surface loss. Why not ... Coropuna's ice cap expanded to over 500 square kilometres (190 sq mi) during the last glacial maximum, but has been in retreat since 1850. [43] The highest point of the Coropuna ice cap is measured at 6,446 metres (21,148 ft) altitude. [10] Mapping of the volcano is made difficult by the ice cap. [51], Coropuna is drained by deep gorges, with water eventually reaching the Arma and Majes rivers, both of which empty into the Pacific Ocean.
After the recovery of three new cores from the Quelccaya ice cap, the OSU team proceeded to the Coropuna ice cap located southwest of Quelccaya in the Western Andean Cordillera (15º 32'S; 72º 39' W). [18] Coropuna, Sara Sara, and Solimana are close to the northern border of the CVZ, where the Benioff zone becomes shallower.
