Port Vila, October 20 (QNA) - An earthquake measuring 5.0 on the Richter scale, struck on Tuesday off the coast of Vanuatu Islands in the Pacific Ocean.

The United States Geological Survey (USGS) said that the earthquake occurred 205 kilometers from the town of Port Olry, at a depth of 10 kilometers.

Vanuatu, a volcanic archipelago in the South Pacific, lies along the "Ring of Fire", where tectonic plates meet and friction between them causes seismic activity. (QNA)
