ANCHORAGE, Alaska - A strong earthquake shook southeastern Alaska early Thursday, but there was no danger of a tsunami and no early reports of any damage, officials said.
The magnitude 6.0 quake struck shortly before 1 a.m. and was centered in the ocean, about 200 miles south of the capital, Juneau, the U.S. Geological Survey said.
The Tsunami Warning Center said there was no danger of a tsunami.
The quake was widely felt across the region, but the Alaska Earthquake Information Center said it had no immediate reports of any damage.
The police dispatch office in the coastal town of Craig, 60 miles east of the epicenter, said the quake was felt but it had received no calls about damage or other problems.
Still, the USGS said the quake was strong enough to have an effect.
The center says the quake is an aftershock to a magnitude 7.5 temblor that struck on Jan. 4.
That quake sparked a tsunami warning for hundreds of miles along the Alaska and Canadian coasts, but it was canceled after a few hours when no damaging waves were generated.
