Magnitude 6.0 earthquake hits off Alaska coast; no reports of damage

A powerful earthquake struck off the coast of southeastern Alaska early Thursday, but there were no immediate reports of injury or serious damage.

The magnitude 6.0 quake hit at 4:53 a.m. ET about 70 miles off the coast, near Port Alexander on Baranof Island, the U.S. Geological Survey said.

The strongest shaking was most likely felt in the small town of Klawock, on Prince of Wales Island to the south of Port Alexander, but the quake was also felt in Ketchikan, Sitka and the capital, Juneau, which is about 190 miles away, the USGS said.

The earthquake occurred eight miles below the ocean surface, but there was no danger of a damaging wave, according to the U.S. government's West Coast and Alaska Tsunami Warning Center.
