USGS provided following detail info about the Magnitude 7.1 Araucania, Chile earthquake:
January 2nd, 2011,
According to the USGS, January 2nd 2011 earthquake occurred at the southern end of the aftershock region of the Mw 8.8 megathrust earthquake of February 27, 2010, and can also be considered an aftershock of that event.
USGS reported that today's earthquake for Araucania, Chile earthquake occurred as a result of shallow thrust faulting on or near the subduction interface between the Nazca and South America tectonic plates. At the location of this event, the Nazca plate moves east-northeastwards with respect to South America at a rate of approximately 74 mm/yr. The Nazca plate, oceanic in origin, subducts beneath the South America plate at a shallow angle along the Peru-Chile trench, and is seismically active to depths of approximately 200 km near the epicenter of today's earthquake, through further north seismicity continues to depths exceeding 600 km.
There are no immediate reports of major damage or injury.
