An earthquake of magnitude 8.2 was recorded on Wednesday at night off the coast of the Alaska Peninsula, reported the United States Geological Survey (USGS), which triggered a tsunami warning.
The tremor occurred at 91 km southeast of Perryville Townshipexplained the USGS, whose tsunami warning affects southern Alaska and the Alaska Peninsula.
Perryville is a small town located about 800 km from Anchorage, the largest city in Alaska.
The United States government activated a tsunami watch for Southeast Alaska.
At first, the US tsunami warning system warned that “dangerous waves” could occur, but two hours later it updated its forecast and stated that the eventual waves would not exceed 30 centimeters.
On Kodiak, an island off the coast of Alaska and inhabited by about 6,000 people, tsunami alerts were activated, and authorities warned that the tsunami could occur around 11 p.m. local time.
But none were recorded in the end, according to local radio KMXT.
In some videos published on social networks by journalists and residents of the area, Kodiak locals seen driving awayfrom the coast, with the sound of alarms in the background.
Too a tsunami warning was activated for Hawaii, where residents were asked to stay away from the beach, but two hours later it was deactivated.
They registered five aftershocks in the subsequent 90 minutes to the earthquake, the largest with a magnitude of 6.2, according to the USGS.
In October, a 7.5 magnitude earthquake caused tsunami waves off the southern coast of Alaska, but no damage was reported.
Alaska is located in the Pacific “Ring of Fire”, an area with frequent seismic activity where tectonic plates collide.
Alaska was hit by a 9.2 magnitude earthquake in March 1964, the strongest ever recorded in North America. It devastated Anchorage and spawned a tsunami that swept across the Gulf of Alaska, the west coast of the United States and Hawaii.
More than 250 people lost their lives in the earthquake and tsunami that followed.
