Like most stratovolcanoes in the Southern Volcanic Zone of the Andean Volcanic Belt , Puyehue and Cordón Caulle are along the intersection of a traverse fracture with the larger north-south Liquiñe-Ofqui Fault . The volcanic complex has shaped the local landscape and produced a huge variety of volcanic landforms and products over the last 300,000 years . Cinder cones , lava domes , calderas and craters can be found in the area apart from the widest variety of volcanic rocks in all the Southern Zone , for example both primitive basalts and rhyolites . Cordón Caulle erupted shortly after the 1960 Valdivia earthquake , the largest recorded earthquake in history
