A strong earthquake struck in a remote region off the Alaska coast, but there was no threat of tsunami or immediate reports of damage, officials said Friday.

The magnitude-6.7 quake struck at 11 p.m. Thursday and was centered in the ocean about 35 miles beneath the seabed and some 400 miles southwest of Anchorage, the U.S. Geological Survey said. It hit a remote and lightly populated Aleutian Island region.

The temblor was felt on the Alaska Peninsula and Kodiak Island, more than 100 miles away.

The "earthquake lasted a minute -- max," Kodiak resident Don Roberts told the Kodiak Daily Mirror. "We're up for the next two hours talking about it."

The police dispatch office in Kodiak says the quake was felt at the station, but it received no reports of damage.

Several aftershocks of magnitude-3.0 or greater followed the larger shaking, the Geological Survey said.

There is no tsunami danger, according to the National Tsunami Warning Center.
