The US Geological Survey (USGS) reported that a 7.9-magnitude quake struck off the coast of Alaska, 280 km southeast of Alaska's Cody Island, Alaska.
The depth of the circle is 25 km.
The European Mediterranean Seismic Center (EMSC) said the magnitude and depth of the earthquake were 7.6 and 10 km, respectively.
CNN reported that a tsunami warning was issued in the British Columbia province of British Columbia, citing the Tsunami Alert Center and the Aleutian archipelago, which stretches west from the Alaska Peninsula and the Alaska Peninsula in southeastern Alaska.
There were also tsunami warnings in western California, Oregon, and Washington state.
According to the Honolulu Emergency Management Department, a tsunami warning was issued on the Hawaiian Islands far southward from the earthquake, and was then released.
"I heard that a tsunami warning had been issued, and I was evacuated from the ship with others, and the entire village was evacuated," said Nurse Moore, who was aboard the ship on Cody Island.
Heatherland from Anchorage said, "It seemed to be the longest lasting earthquake I've ever experienced."
The New York Times (NYT) said the earthquake was the largest in almost seven years after a 9.0 magnitude earthquake in Japan.
