No, neither did we. After the powerful earthquake off the coast of Kamchatka, Russia, on July 30 (local Russian time), scientists warned of tsumani waves threatening the west Pacific Coast of North America. These waves were predicted to transit the ocean and strike Southern California beaches and harbors by 1:30 AM on July 30 and were observed to create stronger waves at that time, but no surface damage was reported. Erratic waves were measured between 1:00 AM and about 2:00 PM at San Diego’s Broadway and Scripps Piers.

John Dumas of the National Oceanic and Atmospheric Administration, NOAA, said, “The only area in California to get a tsunami warning was the Crescent City area. That would trigger EAS. We had a Tsunami Watch which was transitioned to an Advisory in SoCal which does not trigger EAS.”

Damage estimated at $1-million was done to the harbor at Crescent City, California on the Oregon border, a town known for its vulnerability due to its low elevation. 

Several San Diego area engineers confirm that Tsunami Warnings were neither received nor issued by the radio and TV stations they maintain. 

Exactly what triggers EAS codes for tsunamis? NOAA has a protocol and operates two warning centers but what triggers codes for what regions is complex.
