Volcán Socompa is a massive, 6051-m-high dacitic stratovolcano noted for an eruption about 7200 years ago, similar to that at Mount St. Helens in 1980. The Socompa eruption produced a massive 600 sq km debris-avalanche deposit, much larger than at St. Helens, that extends about 40 km from the summit. This view from the north shows dark-colored post-collapse lava domes on the right side that have filled much of the head of the massive collapse scarp, which extends to the base of the volcano at the lower right.

This dramatic NASA Space Shuttle image (with north to the upper right) is of Socompa volcano. A large horseshoe-shaped caldera breached to the NW was the source of a major debris avalanche about 7000 years ago that extended beyond the upper left margin of the image. Young dacitic lava domes and flows partially fill the collapse amphitheater, and prominent lava flows with flow levees are visible on the outer flanks of the 6051-m-high volcano.
