Tsunami drill to be held along Mendocino Coast Wednesday
A tsunami drill will be held along the Mendocino Coast on Wednesday, the Mendocino County Office of Emergency Services said. Organized by the county, National Weather Service and the Redwood Coast Tsunami Work Group, the annual event tests the readiness of coastal residents if a tsunami is expected. The drill will also take place along the coasts of Humboldt and Del Norte counties. The drill comes two days after San Mateo County launched its new Tsunami Hazard Area Dashboard on as part of a broader effort to better prepare for future tsunamis following last December's chaotic response to a regional tsunami warning . The weather service issued a tsunami warning after a 7.0-magnitude earthquake struck off the coast of Humboldt on December 5, 2024 . No tsunami surge was reported, and the warning was canceled within an hour of being issued. An emergency alert will be sent via text message to coastal areas at approximately 11 a.m. Wednesday. The message will ask residents to practice their tsunami evacuation plan by moving from low-lying coastal areas. According to the Redwood Coast Tsunami Work Group at Cal Poly Humboldt, tsunami hazard zones include beaches and waterways, including Noyo Harbor in Fort Bragg, Arena Cove in Point Arena, and parts of Mendocino and Manchester. Maps of tsunami hazard zones can be found online . Residents not in tsunami hazard zones will be asked to practice their earthquake safety procedures. The drill will not include a test of the tsunami sirens, the county said. Residents can register for emergency alerts at .

Tsunami could flood ‘sizeable areas' of coastal Los Angeles County, experts say
Officials are cautioning residents to check whether they live in a tsunami zone ahead of Tsunami Preparedness Week, and there's a grim outlook for some of coastal SoCal should worse come to worst. The California Department of Conservation has released Tsunami Hazard Area maps and data that show the risk of a tsunami for coastal communities from the Mexico border to the Oregon state line. The most recent data for L.A. County was published in 2021 and indicates that a large tsunami could flood 'sizeable areas' of Marina del Rey and Long Beach to an elevation of 15 feet, according to Rick Wilson, head of the California Geological Survey's Tsunami Program. '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 stated. 'Local officials have indicated that if both ports were shut down for one day, the economic loss to the county would be over $1 billion.' Tsunami Hazard Area maps can be viewed for Los Angeles, Orange and Ventura counties. To view all California counties, click here. California's Tsunami Preparedness Week is March 22 through March 30.
