Tralcán

Tralcán (mapudungun for thunder) is a triangular-shaped mountain, which is located near Riñihue Lake, Chile. It is located south of the outflow dividing western Riñihue in two arms. Despite having been sacred to the huilliches for centuries, the mount became famous when several landslides near Tralcan dammed the Riñihue Lake after the 1960 Valdivia earthquake. The water levels in the lake rose more than 20 m and became a threat to the existence of Valdivia city. These events came to be known as The Riñihuazo ("El Riñihuazo" in Spanish). There is evidence that a similar landslide occurred after the 1575 Valdivia earthquake.
