Today's quake was centered 50 kilometers northwest of Concepcion, and was relatively shallow at 20 kilometers under sea level. But Chile's navy announced that it wasn't the kind of quake to generate a deadly tsunami of the kind that ravaged nearby coastal cities when an magnitude-8.8 quake devastated Chile in 2010.
The US Geological Service says the quake struck at 1.04pm local time (1604 GMT). Chile's national emergency office says there are no immediate reports of injuries or damage.
