At approximately 1:49:36 am Alaska Time, a 7.0 magnitude earthquake was reported off the coast of Southeast Alaska 65 miles WSW of Craig, Alaska. The epicenter was reported at Latitude N54.95 & Longitude W134.53 at a depth of 20 miles. The center was located 70 miles NW of Dixon Entrance.
Within seconds, at 1:49:48 am Alaska Time, a second 6.7 magnitude earthquake was reported off the coast of Southeast Alaska 57 miles WSW of Craig, Alaska. The epicenter reported at Latitude N55.02 Longitude W134.36.
According to NOAA's West Coast and Alaska Tsunami Warning Center, based on the location and magnitude, the earthquakes were not sufficient to generate a Tsunami damaging to California, Oregon, Washington, British Columbia or Alaska. Some areas may experience small sea level changes. However, the Pacific Tsunami Warning Center will issue Tsunami bulletins for Hawaii and other areas of the Pacific.
One earthquake of a magnitude of 7.0 was reported by the Federal Aviation's Flight Service Station in Ketchikan based on information they received from Palmer's Alaska Tsunami Warning Center. Two earthquakes of 7.0 and 6.7 were reported by the USGS Earthquake Hazards Program.
No further information is available this morning.
The first reports of two earthquakes were released shortly after 1 am Monday morning. Shortly after 3 am Monday morning, only one earthquake was being reported by the Alaska Earthquake Information Center with a magnitude of 6.8. The USGS updated their earlier reports of two quakes of 7.0 and 6.7 and revised their report Monday to one earthquake of a magnitude of 6.7.
