After Japan was ravaged by an earthquake and tsunami, scientists decided to figure out what would happen if the same thing hit the U.S.
If a magnitude 9.1 earthquake strikes off the Alaskan Peninsula. it would send a massive tsunami straight for our Pacific coast.
That means three hours to evacuate 750,000 people before waves up to 22 feet high hit the shore.
If the tsunami came at high tide, one third of the boats in the California's marinas would be destroyed, causing more than $700 million in damage.
Low-lying coastal cities like Seal Beach and Huntington Beach in northern Orange County would be among the worst hit.
Emergency responders say this research is invaluable to their preparation.
