A tsunami watch has been issued for Hawaii this evening following a large earthquake off the Alaska Peninsula.
The Pacific Tsunami Warning Center listed the magnitude as 8.1 and said “an investigation is underway to determine if there is a tsunami threat to Hawaii.”
The U.S. Geological Survey listed the magnitude at 8.2 and said the quake struck at about 8:15 p.m. (Hawaii time) and was centered 56 miles east-southeast of Perryville, on the Alaskan Peninsula, which is under a tsunami warning. The quake was about 29 miles below the surface of the ocean, according to USGS.
“Based on all available data a tsunami may have been generated by this earthquake that could be destructive on coastal areas even far from the epicenter,” PTWC said.
The estimated earliest arrival of the first tsunami wave in Hawaii is 12:53 a.m. Thursday.
