A forceful 6.2 magnitude earthquake struck Chile on Wednesday off the country's south-central Pacific Coast, the U.S. Geological Survey reported.
There were no immediate reports of deaths or major damage, and there were no tsunami warnings from the Pacific Tsunami Warning Cent in Hawaii.
The quake hit at 1255 GMT at a depth of nine miles, off the coast of the Bio Bio region, 60 miles west of the city of Concepcion.
The same area was badly damaged in a major 8.8 magnitude quake that struck Chile on 27 February 2010.
The USGS original reported a magnitude 6.4 for Wednesday's quake, but it was later downgraded to a 6.2.
A second 5.2 magnitude aftershock followed around 50 minutes later.
"There have been no reports of injuries, disruption of basic services or damage to infrastructure as a result of this earthquake," the national office of emergencies Onemi reported.
Last year's quake was followed by a tsunami that devastated coastal communities. That disaster - the sixth largest earthquake on record since 1900 -- killed 524 people, left 220,000 homeless and caused an estimated $30 billion in damage.
