Tsunami advisories and warnings were issued from the California-Mexico border up to the British Columbia-Alaska border soon after the earthquake, which happened around 4:30 p.m. PDT. The National Tsunami Warning Center confirmed waves over 1 meter near the California-Oregon border. The first significant waves reached Long Beach, Washington at 11:45 p.m. and Los Angeles Harbor at 1:05 a.m. on July 30. Experts warn that tsunami activity could last up to 20 hours, and the first wave is not always the largest.
Current Status and Safety Measures
No major damage or serious injuries have been reported, but several minor injuries occurred. The tsunami advisory for parts of Southern California has been cancelled, but most of the West Coast remains under advisory. Residents and visitors are strongly urged to:
- Stay away from beaches, harbors, and marinas until all advisories are lifted.
- Avoid watching the tsunami; even small surges can be deadly. Six inches of fast-moving water can knock down an adult, and two feet can move a car.
- Boaters should leave harbors and seek higher ground.
The National Weather Service uses a four-level alert system: Information Statement, Advisory, Watch, and Warning. The Oregon-California border briefly reached the highest threat level, meaning dangerous flooding and strong currents were possible. Most of the West Coast remains under an Advisory, which means strong currents and unpredictable waves are expected, but widespread flooding is not likely.

Travel and Community Effects
Airports along the West Coast, including Los Angeles, San Francisco, Portland, and Seattle, have issued travel advisories. No major airport closures have been reported, but travelers should check with airlines and airport authorities for updates. Coastal infrastructure, such as marinas and waterfront businesses, may face temporary closures or restricted access.
Expert and Community Responses
Seismologists and tsunami experts stress that even small tsunami waves can be deadly due to their speed and force, especially in harbors and low-lying areas. Emergency officials urge everyone to follow official warnings and not underestimate the risk, as tsunamis can bring multiple waves over many hours. Local business owners and residents worry about economic impacts, especially in tourism areas, but agree that safety comes first.
Background and Outlook
This is one of the most significant tsunami threats to the U.S. West Coast in recent years, triggered by one of the largest earthquakes ever recorded in the region. Tsunami advisories are expected to remain in effect for several more hours, with updates from ocean monitoring systems. Authorities will continue to watch for aftershocks and more waves, and will lift advisories only when it is safe.
