On June 14, a tsunami warning was issued after a 7.2-magnitude earthquake hit off the Northern California coast. In Newport Beach, lifeguards went to work to get people off the beaches and piers, and a voluntary evacuation was announced.
Lifeguards were also watching for tsunami waves and communicating with the Coast Guard to learn if any waves had been detected, Freeman said.
Parker said one problem that local agencies faced during that 78-minute tsunami warning on June 14 was seemingly contradictory information from the National Weather Service's Tsunami Warning System. The warning center in Alaska, which monitors tsunami risk along the West Coast, provided the warning. Another warning center in Hawaii indicated there was no risk of a tsunami.
