Chile - January 9th, 2011

Visible at the center of this orthorectified image is Maipo, a stratovolcano in the Andes, lying on the border between Argentina and Chile. It is located 90 km south of Tupungato and about 100 km southeast of Santiago.

Maipo retains a symmetrical, conical volcanic shape, unlike many of the other nearby peaks, making it the best known peak in the region, though it is not the highest. (Nearby Castillo is 5,485 m high.) Maipo is also almost the southernmost 5,000 metre peak in the Andes. (That honor goes to Sosneado, about 50 km to the south).

Maipo is located within the Diamante Caldera, a feature of about 15 km by 20 km size that is about one-half million years old. It rises about 1,900 m (6,230 ft) above the floor of the caldera. Immediately to the east of the peak, on the eastern side of the caldera floor, is Laguna del Diamante, a picturesque lake that formed when lava flows blocked drainage channels from the caldera in 1826. The lake covers a surface area of about 14.1 kmĀ² and is one of the largest freshwater resources in the Province.

Detail of volcanoes

Detail of volcanoes

Many volcanoes can be seen, capped with snow, in the Andes Mountains in Chilean Patagonia.

While the main image shows a general view of the area, from the Pacific Ocean, across Chile and the Andes, into Argentina, the first image detail contains a close-up look at the many volcanoes and lakes.

The second close-up focuses on Maipo, a stratovolcano north of Patagonia lying on the border between Argentina and Chile. It is located about 100 km (60 miles) southeast of Santiago.

Maipo retains a symmetrical, conical volcanic shape, unlike many of the other nearby peaks. Some smoke is visible blowing westward from near the volcano, though it is unclear if it is being vented from Maipo itself or caused by forest fires in the area.

The grey area surrounding the volcano is the Diamante Caldera, a feature of about 15 km by 20 km size. On the eastern side of the caldera floor, is the Laguna del Diamante, a lake that formed when lava flows blocked drainage channels from the caldera in 1826.
