The Center initially warned of hazardous waves, however, about two hours later, it gave an update that the forecast maximum height of any Tsunami will be less than 1 foot (30 centimeters) above tide levels.
The sirens of Tsunami warnings were also broadcast across Kodiak. An island with a population of about 6,000 people, along Alaska’s coastline. The Center had said that any potential tsunami will hit Kodiak at about 11.55 pm.
Initially, the tsunami watch was issued for Hawaii meaning that the residents were required to stay away from the beaches, however, the watch was lifted about two hours later.
