Antillanca Volcanic Complex
About Antillanca Volcanic Complex
The Antillanca Volcanic Complex is a cluster of late-Pleistocene to Holocene basaltic-to-andesitic scoria cones, maars, and small stratovolcanoes covering an area of 380 km2 SE of Lago Puyehue and NE of Lago Rupanco. The most prominent edifice is the Holocene Casablanca stratovolcano, which has a truncated conical profile and produced major explosive eruptions about 2,910 and 2,260 radiocarbon years ago. Older late-Pleistocene stratovolcanoes, such as Sarnoso to the SW and Fiuchá to the NW, are extensively dissected by glaciers. Fissures oriented in four major directions influence the orientation of the cones. Thermal areas are found in scattered locations on the NW side of the complex.
