The US government’s National Tsunami Warning Center also issued a tsunami alert for south Alaska and the Alaskan peninsula. Tsunami warning sirens were broadcast across Kodiak. Kodiak has a population of about 6,000 people. As per the estimate, the tsunami would hit Kodiak at about 11:55 pm.

The forecast about the maximum height of any tsunami would be less than 1 foot (30 centimetres) above tide levels.

Initially, a tsunami watch was initially issued for Hawaii. But later it was lifted.

Alaska is part of the seismically active Pacific Ring of Fire.

In March 1964, Alaska was hit by a 9.2-magnitude earthquake which is the strongest ever recorded in North America. More than 250 people were killed by the quake and the tsunami.

In October 2020, a 7.5 magnitude earthquake caused tsunami waves in Alaska’s southern coast. But no casualties were reported.
