7.1 Magnitude Earthquake Hits Araucania, Temuco in Central Chile

January 2, 2011: The U.S. Geological Survey reports that an earthquake measuring 7.1- 7.2 on the Richter Scale hit Arcaucania in central Chile Sunday at 20:20:16 UTC (3:20 p.m. EST). The earthquake’s epicenter was

about 45 miles northwest of Temuco, Araucania in Chile. Temuco is 370 miles southwest of Santiago. The earthquake depth was about 16.9 km (10.5 miles deep). On New Year’s Day, January 1, 2011 a 7.0 magnitude earthquake hit 160 miles northeast of Santiago del Estero in Argentina at 4:46 a.m. EST (9:56 Universal Time Coordinated). There were no reported injuries in either earthquake.

Reports of the 2011 Chili Earthquake differ in Richter Scale measurment from 7.1-7.2 with the consensus being on 7.1 magnitude. Based on other reporting errors in Reuters first report, including 7.2 magnitude, and wrong geographical information, 7.1 is the correct magnitude. Tremors were felt as far away as Chile’s capitol of Santiago. Not damage has been reported and the Pacific Tsunami Warning Center reports that no widespread threat of a follow-up tsumami eisits, but did warn that minor tsunamis may occur around the epicenter of the quake. Major magnitude earthquakes can be followed up by a tsunami in the ocean.
