An earthquake with a preliminary magnitude of 7.1 struck Friday morning off the coast of Alaska, according to the U.S. Geological Survey.

The quake was reportedly 6.2 miles deep, a characteristic which forecasters say has relatively low chance of causing damage.

The state emergency response center was staffed early Friday morning.

The epicenter was in the Aleutian Islands, about 120 miles from Atka, Alaska.

The quake prompted a tsunami warning for coastal areas of Alaska, from Unimak Pass, Alaska to Amchitka Pass, Alaska, the West Coast and Alaska Tsunami Warning Center said.

There were no immediate reports of damage or injuries in the sparsely populated area near the epicenter.

In Alaska, the main industry is fishing.

Residents began evacuating to higher ground in Atka Friday morning but then stopped after the cancellation, Zidek told reporters.

In June, an earthquake with a magnitude of 7.2 in the same area of the Aleutians also prompted a tsunami warning, Associated Press press reports.
