Earthquakes occur at any fault line, but the most destructive earthquakes happen at subduction zones. “Great earthquakes” of Mw 8.0 or more occur only about once a year and stronger earthquakes are scarcer still. The 1960 Valdivia Earthquake On 22nd May 1960 (14:11 Chile time, 19:11 GMT), the greatest earthquake ever recorded in history, with magnitude of 9.5 degrees on the Richter scale, shocked the coastal regions of southern Chile. In 2010 an 8.8-magnitude followed by a … The most powerful quake recorded in the last century or so, when accurate estimates of magnitude have been possible, was a truly massive event estimated by the United States Geological Survey to have had a magnitude of Mw 9.5. The nearby towns of Valdivia and Puerto Montt suffered devastating damage because of their closeness to the center of such a massive quake. Huge earthquake hits Chile On May 21, 1960, the first tremor of a series hits Valdivia, Chile. In fact, the largest earthquake of this century was in Valdivia Chile, on May 21st 1960. the 1960 earthquake the city held a population of 72400. The 9.5-magnitude 1960 Valdivia earthquake was the strongest ever recorded on the magnitude scale, according to the USGS. But it was also the site of the largest earthquake ever recorded – in the small, southern city of Valdivia in 1960. By the time they end, the quakes and their aftereffects kill 5,000 people and leave another 2 … https://worldhistoryproject.org/1960/5/22/valdivia-earthquake-of-1960 Nestled within the Circum-Pacific Belt, the Valdivia Earthquake was the most powerful in a series of quakes that struck the region, measuring at a magnitude of about 9.5. Valdivia experienced three distinct hazards due to the 1960 earthquake; strong ground shaking, tectonic subsidence, and tsunami inundation. The 1960 Valdivia earthquake or Great Chilean Earthquake is to date the most powerful earthquake ever recorded in Earth’s history, rating 9.5 on the moment magnitude scale. The 1960 Valdivia earthquake or Great Chilean Earthquake (Spanish: Gran terremoto de Valdivia) of 22 May 1960 is to date the most powerful earthquake ever recorded, rating 9.5 on the moment magnitude scale. Siesmicity has shown us that Chile has continual earthquakes year in and year out, some much bigger than others. Dietrich Lange, Javier Ruiz, Sebastián Carrasco, Paula Manríquez, The Chiloé Mw 7.6 earthquake of 2016 December 25 in Southern Chile and its relation to the Mw 9.5 1960 Valdivia earthquake, Geophysical Journal International, 10.1093/gji/ggx514, 213, 1, (210-221), (2017). The epicenter of the earthquake (the point on the earth's surface directly above the focus of an earthquake) was 60 meters down below the ocean floor about 100 miles off the coast of Chile out in the Pacific. The epicenter of the Valdivia earthquake was near Canete, 900 km (435 mi) south of the capital, Santiago, but was named after the city that took the biggest hit. This study will focus on the first two by characterizing the ground failure due to the strong In addition to causing devastating tremors on land, the earthquake also generated a deadly tsunami, reaching up to 80 feet high.
