ANCHORAGE, Alaska (Reuters) - An earthquake of 6.1 magnitude rocked a portion of Alaska's eastern Aleutian Islands on Saturday, but no tsunami warning was anticipated and there were no reports of damage, officials said.

The earthquake was centered about 50 miles southwest of Sand Point, a fishing community with nearly 1,000 residents, said the West Coast and Alaska Tsunami Warning Center in Palmer, Alaska.

"We really don't expect any damage," said James Waddell, a physical scientist with the center. "I'm sure that the locals felt it, but that's kind of the extent of it."
