The U.S. Geological Survey (USGS) said Thursday that a magnitude-4.5 earthquake has rattled Hawaii's Big Island, as two hurricanes rumbled toward the islands. The temblor struck on the north tip of the Big Island, roughly 11 kilometers from Waimea early Thursday. USGC initially announced the quake was magnitude-4.3 and quickly upgraded it. Hawaii County Civil Defense Director Darryl Oliveira said that there have not been any reports of damage. He said that a moderate quake is "not uncommon" for Hawaii. Hurricane Iselle was on course to hit the Big Island late Thursday, and was being tailed by Hurricane Julio, which strengthened early Thursday into a Category 2 storm.
