A magnitude-6.7 earthquake struck Peru's central Pacific coast on Friday, but authorities here said they received no reports of casualties or significant damage.

The temblor occurred at 13:54 p.m. (1854 GMT) and its epicenter was 30 kilometers (18 miles) below the ocean floor at a spot about 117 kilometers (72 miles) southwest of the coastal city of Ica, scientists at the Peru Geophysical Institute told Efe.

Though the quake was strongest in Ica and Nazca, it was felt as far away as the southern interior city of Cuzco.

Residents of Ica said they lost power briefly after the earthquake, while telephone service was disrupted in Lima and other coastal cities.

The Ica region bore the brunt of the catastrophic 2007 quake that left more than 500 people dead.

Four years later, hundreds of people in cities such as Ica, Pisco and Chincha are still living in tents as they wait for the reconstruction of homes destroyed by the magnitude-7.9 temblor.
