Santiago: A 7.0 magnitude earthquake rattled central Chile on Friday, the US Geological Survey said, striking close to a zone hit by a devastating quake a year ago and shaking buildings in the capital Santiago.

"For the moment there are no reports of any damage or injuries," a spokesman for government emergency agency Onemi said.

"The Navy alert center says there is no risk of a tsunami," he added.

Some residents fled into the street in parts of south-central Chile.

The offshore quake was 45 km north of Concepcion and 18.4 km deep, the USGS said. It was 392 km south-southwest of Santiago, it said.

An 8.8-magnitude earthquake and ensuing tsunami struck Chile on February 27 last year, killing about 500 people and wrecking infrastructure across central-southern areas of the country.
