There, just outside La Pasada, Tulio Ruiz found crosses and a full casket. Various studies have placed it at 9.4-9.6 on the moment magnitude scale. [20] This magnitude 7.7 earthquake probably occurred along the Liquie-Ofqui Fault, meaning that the fault would have moved as a consequence of the 22 May Valdivia earthquake. The main tsunami crossed the Pacific Ocean at a speed of several hundred km/h and devastated Hilo, Hawaii, killing 61 people. In interviews several decades later, people in Chile, Hawaii, and Japan recall the tsunami. A 2019 research paper postulates that the Liquie-Ofqui fault had a Mw9.07 strike-slip subevent along with the main Mw9.37 main thrust sub-event which could help account for how the plate boundary event seemingly "over spent" its tectonic budget. Each meter the water level rose was equivalent to 20million cubic meters, which meant that 480million cubic meters of water would release into the San Pedro River (easily overpowering its flow capacity of 400 cubic metres (14,000cuft) per second if it rose above the final, 24-meter-high dam.

The Nazca Plate is an oceanic tectonic plate in the eastern Pacific Ocean basin off the west coast of South America. The earthquake did not strike all the territory with the same strength; measured with the Mercalli scale, tectonically depressed areas suffered heavier damage. The chapter also discusses the extent and effects of the hazards; their . While the above phase correction method successfully accounts for the dispersion effect of recent tsunamis such as the 2011 Tohoku earthquake recorded in deep ocean bottom pressure gauges (Ho et . Although a neighbor quickly took that route, the Navarro family stayed in their home, beside another tidal stream. National Geographic Headquarters 1145 17th Street NW Washington, DC 20036.
