"A tsunami was generated during this event but no longer poses a threat," the center said.
The Alaska Earthquake Information Center said the quake was widely felt but it received no reports of any damage.
"It was the most intense earthquake I've felt in my 10 years here. I'm pretty sure there was stuff falling off of shelves," Chief Schmitt said. "There is no report of any wave activity here."
He said that an evacuation sirens and announcements came shortly after the quake, prompting the temporary rush to higher ground.
Some people in Craig also moved to safer territory.
"Several citizens elected on their own to move to higher ground. Several locations in Craig were set up for staging (and) shelter," said Chief Ely, adding that "no evacuation was ordered."
In addition to the warning, a tsunami advisory was briefly in effect for some Alaska coastal areas to the north of the warning zone, as well as to the south of the zone, from the Washington state border to the northern tip of Vancouver Island.
A tsunami warning means an area is likely to be hit by a wave, while an advisory means there may be strong currents, but that widespread inundation is not expected to occur.
