Abstract:

Intertidal deposits show net late Holocene emergence along the Pacific coast near Maullin and Carelmapu, Chile (latitude 41.6°-41.7°S). The maximum amount of net emergence is about 1 m in the past 1500 years and 2 1/2 m in the past 4000 years. Emergence has prevailed despite sudden submergence that has changed marshes into tideflats, most recently during a magnitude-9.5 earthquake in AD 1960.
