The U.S. Geological Survey says a magnitude 6.7 earthquake has hit the South Pacific island nation of Vanuatu. There are no reports of damage or injuries.
The monitoring agency says the earthquake hit just after 6 p.m. local time and was centered 129 miles (208 kilometers) southeast of Port Vila, the capital. It hit at a depth of about 19 miles (31 kilometers). The agency originally said the quake was 7.1, but revised the magnitude downward.
The region lies on the "Ring of Fire" _ an arc of earthquake and volcanic zones that stretches around the Pacific Rim. About 90 percent of the world's quakes occur in the region.
