Japan has ordered 1.9 million people to evacuate, warning that tsunami waves could continue for more than a day.
It came as workers were evacuated from Fukushima nuclear power plant.
After the 2011 triple disaster, resulting in a nuclear meltdown, an alert in the Fukushima area always comes with an intense sense of fear.
The Tokyo Electric Power Company was one of the first organisations to evacuate its workers.
Japanese authorities have plans in place for those within 20 kilometres of the plant with nuclear debris next to the plant.
Meanwhile, Hawaii's emergency management has warned locals to remain outside the evacuation zone until further notice.
The zone wraps around the entire coastline.
On the California coast, the small community of Crescent City has turned on its tsunami sirens.
"You are hearing a Tsunami Siren. We are under a Tsunami Warning. Please stay away from beaches and waterways.
"A predicted wave may hit at 11.55pm. We are waiting on additional information about any level of evacuation," Crescent City CA - City Hall posted on Facebook.
A 1964 tsunami sparked by an earthquake in Alaska caused a 21ft high wave to hit the city, which killed 11 people and destroyed its downtown.
