A strong earthquake struck off the coast of the south-central Chilean city of Concepcion on Monday, the same area devastated by a massive temblor two years ago. But there were no immediate reports of damage and authorities said it would not cause a tsunami. The U.S. Geological Survey (USGS) said the magnitude-6.2 earthquake struck 50 kilometers north of Concepcion at 1604 GMT at a shallow depth of 20 kilometers below the seabed in the Pacific Ocean. But the Chilean navy announced that it was not the kind of earthquake to generate a deadly tsunami of the kind that ravaged nearby coastal cities when a magnitude-8.8 earthquake hit Chile in 2010.
