Thousands of villagers who fled their coastal homes during a powerful earthquake in the central Philippines have returned home, but hundreds more still jittery from the temblor remained in evacuation centers Saturday, officials said. The magnitude-7.6 quake struck off the Philippines' east coast late Friday, killing one person in a house collapse, knocking out power in several towns and spurring panic about a tsunami that ended up generating only tiny waves. The quake hit at a depth of 34.9 kilometers (21.7 miles) and was centered 106 kilometers (66 miles) east of Samar Island, the U.S. Geological Survey was quoted as saying by the Associated Press. No large tsunamis were generated by the quake and it caused only minor damage, including cracks on buildings and several bridges, Civil Defense chief Benito Ramos said.
