LIMA, Peru – A large 6.9-magnitude earthquake has struck a sparsely populated area of central Peru, the U.S. Geological Survey said Sunday.

There were no immediate reports of damage or injuries, said Mario Casareto, spokesman for Peru’s fire agency. He said authorities were still surveying the region, including the Ayacucho area where the quake was centred.

The seismological service initially reported the magnitude as 7, but revised it downward to 6.9 in a subsequent report. According to the survey’s updated figures, the quake occurred at 2321GMT Sunday and was centred about 43 kilometres (27 miles) east-northeast of an area called Tambo, and about 467 kilometres (290 miles) southeast of the capital of Lima. It had a depth of 101 kilometres (62.8 miles), the survey said.

Local media said that the quake was felt in parts of Lima and in many major cities of southeastern Peru, including Cuzco and Arequipa.
