COLUMBUS, Ohio - Things are not where they were on the continent of South America, thanks to last month's massive earthquake.
Researchers at OSU and other universities say the magnitude 8.8 earthquake that struck the west coast of Chile last month moved the entire city of Concepcion at least 10 feet to the west, and shifted other parts of South America as far apart as the Falkland Islands and Fortaleza, Brazil.
The preliminary measurements by researchers from four universities and several agencies, including geophysicists on the ground in Chile, paint a much clearer picture of the power behind this temblor, believed to be the fifth-most-powerful since instruments have been available to measure seismic shifts, OSU officials said in a press release Monday..
Argentina's capital of Buenos Aires -- across the continent from the quake’s epicenter -- moved about 1 inch to the west and Chile’s capital, Santiago, moved about 11 inches to the west-southwest, according to Mike Bevis, OSU professor of earth sciences, who has led a project that has been measuring crustal motion and deformation in the Central and Southern Andes since 1993.
