Abstract The Holocene Parinacota Volcanic Debris Avalanche (ca. 8,000 years B.P.) is located in the central Andes of northern Chile. The avalanche formed by the sector collapse of a major stratovolcano adjacent to a lake basin in a single, catastrophic event. The deposit has an estimated volume of ca. 6 km3, a run-out of over 22 km, and covers more than 140 km2 of the surrounding terrain. The values of the Heim coefficient (≈0.08) and the ratio A/V2/3 (ca. 50), where A is the area covered and V… Expand
