WASHINGTON : A 6.1-magnitude quake on Friday rocked the central region of Chile which was hit by the massive February 27 tremor, the US Geological Service said.
The epicentre of the quake, which struck at 1003 GMT, was 65 kilometres (41 miles) south (172 degrees) of Concepcion, Chile, the USGS said. Concepcion is a university town and Chile's second largest city.
The 8.8-magnitude February 27 quake - one of the largest on record - struck off Concepcion, triggering a local tsunami. At least 452 people were killed and the disaster caused some 30 billion dollars in damage. - AFP/ms
