An earthquake with a preliminary magnitude of 6.3 struck Hawaii early Sunday morning, waking up residents and knocking out power, reported The Assocaited Press. The U.S. Geological Survey also reported several aftershocks, including one measuring a magnitude of 5.8. No damage reports were immediately available. The quake occurred at 7:07 a.m. (1607 GMT) local time, 10 miles (16 kilometers) north-northwest of Kailua Kona, a town on the west coast of the Big Island, said Don Blakeman, a geophysicist at the National Earthquake Information Center, part of the U.S. Geological Survey. Blakeman said researchers were still trying to ascertain how many aftershocks struck and how large. Blakeman said there was no risk of a Pacific-wide tsunami, but a possibility of significant wave activity in Hawaii. The quake occurred about 155 miles (250 kilometers) to the southeast of Honolulu, the state capital, in Oahu.
