Laguna del Maule

Laguna del Maule

In the Andean mountain range lies a volcanic caldera named Laguna del Maule. Stretching roughly 15 by 25 kilometers (9 by 15 miles) across, it straddles the border between Chile and Argentina. Within the northern part of the caldera lies Maule Lake, surrounded by a complex volcanic landscape.

This perspective image was assembled from data acquired by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra satellite on April 9, 2003. ASTER produces images using infrared, red, and green wavelengths of light. Vegetated areas range in color from red to pink, snow is white, water is black, and bare rock is earth-toned.

Laguna del Maule holds an assortment of volcanic features, including small stratovolcanoes, lava domes, and cinder cones. Some of the most prominent features surrounding Lake Maule are lava flows, some of which protrude into the lake.

Volcanologists estimate that volcanoes at this site have been active over the past 10,000 years, but the date of the last eruption at Laguna del Maule is unknown.
