A 7.1-magnitude earthquake struck off the South Pacific island nation of Vaunatu Friday, dpa cited the US Geological Survey as saying. The quake hit at 6:10 pm (0710 GMT), 206 kilometres south-east of the capital Port Vila, the organization said online. No damage or injuries were reported, and the Pacific Tsunami Warning Centre did not issue a Pacific tsunami warning. The area is on the Pacific's Ring of Fire, a join between tectonic plates where volcanic activity and earthquakes are relatively frequent.
