The 1960 Chilean earthquake triggered mass movements covering 2.8 percent of Valdivia province

Evidence

The hypothesis that the abundance of Nothofagus in the midand low-elevation Andean forests is largely a consequence of periodic massive disturbances was developed as a direct result of the 1960 earthquake that devastated southern Chile. From May 21 to 25, the Lake District was rocked by 11 earthquakes, each measur­ ing at least 6.0 and one 8.5 on the Richter scale (Wright and Mella, 1963; Saint- Amand, 1962). Associated with this seismic activity were thousands of debris avalanches, landslides, and mudflows, which occurred in a 300- by 1000-km area of the Andes totaling at least 2.8% (25,000 ha) of the land surface of the province of Valdivia (Veblen and Ashton, 1978). — S.
