Coropuna

성층화산 · Peru · 6377m

Nevado Coropuna, Perú's highest and largest volcano, is a massive ice-covered volcanic complex with at least a half dozen summit cones scattered over a 12 x 20 km area. The 6377-m-high summit (left), seen here from the south, is located at the NW end of the complex. Deep, steep-walled canyons surrounding the volcano give it an impressive topographic relief of more than 4000 m over a horizontal distance of 15 km. Several young Holocene lava flows descend the NE, SE, and western flanks.

Nevado Coropuna is a massive ice-covered volcanic complex with multiple summit cones built over a 12 x 20 km area. The summit of the andesitic-to-dacitic complex is a cone at the NW end, north of a line of E-W-trending cones. Deep, steep-walled, canyons surrounding the volcano have produced topographic relief of more than 4,000 m over a horizontal distance of 15 km. Dark-colored younger lava flows descend the NE, SE, and W flanks, but the age of the most recent eruptions are not known. Solfataric activity has been reported.

영어 요약

Coropuna is a dormant volcano located in the Andes mountains of southeast-central Peru. The upper reaches of the compound volcano consist of several perennially snowbound conical summits, lending it the name Nevado Coropuna in Spanish. The complex extends over an area of 240 square kilometres (93 sq mi) and its highest summit reaches an altitude of 6,377 metres (20,922 ft) 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 5,000 metres (16,000 ft), there are various vegetation belts which include trees, peat bogs, grasses and also agricultural areas and pastures.
