Tsunami Threat Could Inundate Major Portions of Coastal Los Angeles, Experts Warn

As California approaches Tsunami Preparedness Week, state officials are raising serious concerns about the potential impact of a large tsunami on coastal Los Angeles County. Recent hazard maps from the California Department of Conservation reveal that vast swaths of popular communities such as Marina del Rey and Long Beach could be submerged under as much as 15 feet of water if a major tsunami were to strike.

Rick Wilson, head of the California Geological Survey’s Tsunami Program, emphasized the gravity of the situation, particularly for critical infrastructure. “Flood levels for the Port of Los Angeles and the Port of Long Beach could reach elevations of 12 to 15 feet, which would inundate almost all of the land in the ports and some of the surrounding communities,” Wilson explained.

The potential ripple effects extend far beyond immediate physical damage. The ports of Los Angeles and Long Beach are two of the busiest in the nation, and a shutdown—even for a single day—could cost Los Angeles County upwards of $1 billion in economic losses, according to local officials.

Tsunami Hazard Area maps show vulnerable zones along the entire California coast, from the Mexico border all the way to Oregon. These maps serve as a critical resource for residents and businesses to assess their level of risk.

With Tsunami Preparedness Week scheduled from March 22 to March 30, emergency officials are urging residents to familiarize themselves with evacuation routes and readiness plans. The sobering reminder is clear: while tsunamis may be rare along California’s coastline, their potential for devastation is immense.

For those living or working near the shore, now is the time to stay informed and prepared.
