A tsunami advisory has been issued for all coastal areas of Los Angeles, Ventura, Santa Barbara, and San Luis Obispo counties, prompting beach closures and warnings for residents to stay away from shorelines. The advisory follows an 8.8-magnitude earthquake that struck off the coast of Russia’s Kamchatka Peninsula.
Expected Wave Activity and Timing
Officials anticipate waves of 1 foot or less will reach Los Angeles beaches and waterways around 1 a.m. on Wednesday, July 30, 2025. These conditions may persist until 10 a.m. The advisory, which serves as the middle tier in the Tsunami Warning Center’s alert system, warns of potential life-threatening currents and dangerous wave activity along the entire West Coast.
Coastal Impact and Warnings
In response to the advisory, authorities are urging all residents to steer clear of beaches, harbors, marinas, and waterways due to the threat of strong waves and hazardous currents. Demonstrating the potential for rapid changes, Port San Luis in San Luis Obispo County is currently experiencing a “rapid and damaging surge,” with tides shifting dramatically within minutes.
Local Closures and Evacuation Advisories
Beaches in both Los Angeles and Long Beach have been closed as a precautionary measure. Residents living in coastal areas have been advised to seek higher ground and to remain vigilant, avoiding the waterline.
City Response and Public Safety Information
Los Angeles Mayor Karen Bass has been briefed on the developing situation and is actively monitoring it. She has urged Angelenos to sign up for emergency alerts to stay informed of any updates or further instructions. The advisory underscores the potential for significant coastal impacts even from distant seismic events, emphasizing the importance of heeding official warnings and staying informed through designated emergency channels.
