Coropuna Volcano — Peru

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.
