The US tsunami warning system also indicated a threat of a tsunami in the Northern Mariana Islands and Guam.
A powerful quake was registered on Thursday, 65 miles southeast of Perryville, Alaska, right offshore of the Aleutian Islands. The United States Geological Survey (USGS) confirmed that the earthquake's magnitude was at least 7.2 but later noted that it may be much stronger, reaching up to 8.2 on the Richter scale.
A tsunami warning was issued by the authorities soon after the tremor.
"Hazardous tsunami waves for this earthquake are possible within the next three hours along some coasts," the US Tsunami Warning System said in a statement.
The National Tsunami Warning Center (NTWC) in Alaska issued warnings for southern parts, the Peninsula, and Pacific coastal areas from Hinchinbrook Entrance to Unimak Pass, while the Pacific Tsunami Warning Center (PTWC) warned of a potential tsunami for Hawaii and the US Pacific territory of Guam.
