It had a moment magnitude of 7.1 and its epicenter was located 23 km on northeast of the city of Constitución, in the Maule Region, Chile.M 7.1 – 23 km NE of Constitución, Chile https://earthquake.usgs.gov/earthquakes/eventpage/usp000jgsw/executive United States Geological Survey According to experts, it was a strong and late aftershock of the Great Chile earthquake of February 27, 2010. The earthquake was felt from Coquimbo to the Los Lagos Region, with the Maule Region being the most affected and causing high commotion in the O'Higgins and Bio-bío regions, which were affected by the earthquake of 2010. Tectonic setting Nazca plate Geology of Chile The earthquake occurred as the result of shallow thrust faulting on or near the subduction interface between the Nazca and South American plates. At the location of this event, the Nazca plate moves east-northeast relative to South America at a velocity of about 74 mm/yr. Jara-Muñoz Julius Melnick Daniel Dominik Brill Strecker Manfred R.

It is seismically active to depths of approximately 200 km (124 mi) adjacent to the epicenter of the March 25th earthquake, though farther north seismicity continues to depths exceeding 600 km on. In historical times the Chilean coast has suffered many megathrust earthquakes along this plate boundary, including the strongest earthquake ever measured, which is the 1960 Valdivia earthquake.Fountain Henry Underwater Plate Cuts 400-Mile Gash The New York Times https://www.nytimes.com/2010/02/28/world/americas/28quake.html 27 February 2010 24 April 2022 https://web.archive.org/web/20100303235619/http://www.nytimes.com/2010/02/28/world/americas/28quake.html 3 March 2010 live More recently, the boundary ruptured during the 2015 Illapel earthquake in northern Chile.Li Zhenhong Lu Zhong Thenkabail Prasad S.
