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

The preliminary magnitude 7.0 quake hit at 9 p.m. Hawaii time in the ocean 70 miles north-northwest of Chirikof Island, Alaska, at depth of 38.3 miles, according to the U.S. Geological Survey website.

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

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

The Pacific Tsunami Warning Center says there is no tsunami danger.

The USGS says there have been five aftershocks of magnitude-3.0 or greater.
