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.
Numerous videos, reportedly showing the quake, were shared by Alaskans on social media.
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 Centre (NTWC) in Alaska issued warnings for southern parts of the state, the Peninsula, and Pacific coastal areas from Hinchinbrook Entrance to Unimak Pass, while the Pacific Tsunami Warning Centre (PTWC) warned of a potential tsunami for Hawaii and the US Pacific territory of Guam.
Meanwhile, authorities of several Alaskan cities, including Homer and Kodiak, recommended locals who are in areas where the tsunami warning is in place to evacuate.
Shortly thereafter, a 6.2-magnitude aftershock was registered off Alaska's coast.
According to the USGS, the aftershock was recorded at 06:23 GMT. Its epicentre was located 137 kilometres (85.12 miles) northwest of Chignik at a depth of 42.2 kilometres. Just a few minutes later, seismologists reported another 5.6-magnitude aftershock 130 kilometres away from Chignik at a depth of 16.5 kilometres.
Alaska is part of the Pacific Ring of Fire, a long horseshoe-shaped seismically active belt of earthquake epicentres. The Ring of Fire is home to 75 percent of the world's volcanoes and 90 percent of its earthquakes.
Back in 1964, Alaska was struck by a 9.2-magnitude earthquake, the strongest ever recorded in North America. The devastating quake unleashed a tsunami that hit the Gulf of Alaska, the US west coast, and Hawaii. Over 250 people were killed by the earthquake and the tsunami.
