An earthquake off the coast of Alaska would cause a tsunami large enough to cause major flooding in Long Beach and parts of Orange County and force 750,000 people to evacuate coastal areas. That's according to an extensive simulation published Wednesday by the U.S. Geological Survey.
The survey highlighted communities across southern California that would be a risk of heavy flooding because of their low elevation and lack of protection from waves. The report is the most extensive look at what such a tsunami would do to California's coastline.
How are Southern California's coastal cities preparing for the possibility of such an earthquake? What is the likelihood of a tsunami like this happening? If a tsunami of this magnitude were to hit the coastline how much damage would it cause?
