WELLINGTON, New Zealand, Rajab 21, 1437, April 28, 2016, SPA -- The U.S. Geological Survey reports that a strong earthquake has rattled the Pacific nation of Vanuatu but there was no tsunami threat and no immediate reports of damage or injuries, according to AP. The magnitude-7 quake hit near Malekula Island. It was centered about 200 kilometers (125 miles) northwest of the capital Port Vila at a depth of 35 kilometers (22 miles), according to the USGS. The Pacific Tsunami Warning Center said there was no threat of a destructive, Pacific-wide tsumani. It was the fourth strong earthquake to strike Vanuatu this month, although none have caused problems. Vanuatu sits on the Ring of Fire, the arc of seismic faults around the Pacific Ocean where earthquakes are common. The nation is also prone to volcanoes and cyclones. --SPA 23:46 LOCAL TIME 20:46 GMT www.spa.gov.sa/w
