MANILA: A powerful 6.5 magnitude earthquake rattled central Philippines on Thursday, United States seismologists said, revising an earlier figure of 6.9. The quake hit at a depth of around six kilometres (four miles), on the central island of Leyte, the US Geological Survey said. There was no immediate warning of a tsunami, the Pacific Tsunami Warning Center said. Large parts of the island of Leyte were devastated by super typhoon Haiyan in November 2013. Huge tsunami-like waves devastated the city of Tacloban and nearby areas, leaving 7,350 people dead or missing. The Philippines lies on the so-called Ring of Fire, a vast Pacific Ocean region where many of Earth’s quakes and volcanic eruptions occur.
