HONOLULU (AP) -- The U.S. Geological Survey reports a magnitude-4.5 earthquake has rattled Hawaii's Big Island, as two hurricanes rumbled toward the islands.<br />
<br />
The temblor struck on the north tip of the Big Island, about 7 miles from Waimea at 6:24 a.m. local time.<br />
<br />
The U.S. Geological Survey initially announced the quake was magnitude-4.3 and quickly upgraded it.<br />
<br />
Hawaii County Civil Defense Director Darryl Oliveira says there haven't been any reports of damage. He said a moderate quake is "not uncommon" for Hawaii.<br />
<br />
A Waimea grocery store employee said the quake didn't cause any apparent damage in the building and didn't knock anything off shelves.<br />
<br />
Hurricane Iselle was on course to hit the Big Island Thursday night, and was being tailed by Hurricane Julio, which strengthened early Thursday into a Category 2 storm.
