(Associated Press) If a monster earthquake struck off Alaska's coast, tsunami waves would rush toward California, crippling the nation's busiest port complex and flooding coastal communities, a report released Wednesday suggests.
The potential impacts, based on a hypothetical magnitude-9.1 jolt off the Alaskan peninsula, were detailed by a team led by the U.S. Geological Survey to help emergency responders prepare.
Tsunamis are a rare but real threat in California. After the 2011 Japan disaster, tsunami waves raced across the Pacific and damaged boats and docks in the commercial fishing village of Crescent City.
