Where Is The Tsunami Warning In California Today? Complete Status Update After Russian Earthquake
Last Updated: July 31, 2025 | Reading Time: 8 minutes
The massive 8.8-magnitude earthquake that struck Russia’s Kamchatka Peninsula on July 30, 2025, sent shockwaves across the Pacific Ocean, triggering tsunami warnings throughout California and the entire West Coast. If you’re wondering where tsunami warnings are currently active in California today, here’s everything you need to know about the latest developments and safety measures.
Current Tsunami Warning Status in California (July 31, 2025)
Breaking Update: All tsunami warnings have since been discontinued in the U.S., with Crescent City being the final U.S. location to discontinue its tsunami warning on Wednesday morning. However, coastal conditions remain potentially hazardous.
Areas Previously Under Alert
The Russian earthquake initially triggered widespread tsunami alerts across California, affecting:
- Los Angeles County – Beaches in Los Angeles County have reopened after tsunami advisories for the West Coast were lifted
- Orange County – Alert lifted as of July 31
- Ventura County – Advisory canceled
- Santa Barbara County – The only advisory still in place is for Santa Barbara County (as of recent reports)
- Northern California Coast – The worst-hit part of California, Crescent City, saw waves max out at eight feet early Wednesday morning
Current Safety Conditions
While official tsunami warnings have been lifted, strong rip currents will remain for the next couple of days, and the weather service for Los Angeles warned beachgoers to check with lifeguards before they enter the water.
Understanding the Russian Earthquake Impact
The Trigger Event
A magnitude 8.8 earthquake struck off Russia’s Kamchatka Peninsula, generating powerful tsunami waves that traveled across the Pacific Ocean. The quake, according to the U.S. Geological Survey, hit at 4:25 p.m. Pacific Daylight Time on July 30, 2025.
Wave Heights Recorded in California
The tsunami reached California with varying intensities:
- Northern California: Waves as high as 3.6 feet were recorded in Crescent City, near the Oregon border
- Crescent City Specifics: Waves max out at eight feet early Wednesday morning — 4 feet from the tsunami on top of a 4-foot high tide
- Statewide Impact: Wave activity peaked at about 3.5 feet in the most affected areas

Understanding California’s Tsunami Alert System
Types of Tsunami Alerts
California uses a three-tier warning system:
- Tsunami Warning (Red)
- Imminent threat or occurring
- Immediate evacuation required
- Dangerous coastal flooding expected
- Tsunami Advisory (Yellow)
- Strong currents and waves expected
- Stay out of water and away from beaches
- No widespread inundation anticipated
- Tsunami Watch (Blue)
- Earthquake occurred, tsunami possible
- Stay alert for updates
- Be prepared to take action
How Warnings Are Issued
The National Weather Service’s Tsunami Warning Centers monitor seismic activity 24/7. When a significant earthquake occurs in the Pacific, they:
- Analyze earthquake data within minutes
- Calculate potential tsunami arrival times
- Issue appropriate alerts based on threat level
- Continuously update status as conditions change
Impact on California Communities
Coastal Response Measures
California communities implemented standard tsunami response protocols:
Beach Closures: All major beaches from San Diego to the Oregon border were temporarily closed or restricted
Harbor Evacuations: Small craft advisories were issued for harbors and marinas
Emergency Services: First responders positioned resources along the coastline
Public Safety Actions
Residents in tsunami-prone areas were advised to:
- Move inland and to higher ground
- Stay away from beaches, harbors, and coastal waters
- Monitor official emergency channels
- Avoid sightseeing at the coast
Why California Faces Tsunami Risk
Geographic Vulnerability
California’s extensive coastline makes it particularly vulnerable to Pacific tsunamis. The state faces potential threats from:
- Pacific Ring of Fire: Earthquakes in Alaska, Russia, Japan, and South America
- Local Sources: Offshore faults like the Cascadia Subduction Zone
- Distant Sources: Major earthquakes across the Pacific Basin
Historical Context
California has experienced significant tsunamis throughout history:
- 1964 Alaska earthquake tsunami caused major damage in Crescent City
- 2011 Japan tsunami caused over $100 million in damages to California harbors
- Regular smaller events from distant earthquakes
Current Conditions and Safety Recommendations
Beach Safety Today
Even with warnings lifted, coastal conditions remain potentially dangerous:
Ongoing Hazards:
- Strong rip currents
- Unpredictable wave patterns
- Debris in coastal waters
- Unstable coastal conditions
Safety Recommendations:
- Check with lifeguards before entering water
- Avoid isolated beach areas
- Stay aware of changing conditions
- Keep emergency supplies accessible
Monitoring Resources
Stay informed through official channels:
- National Weather Service: Real-time alerts and updates
- Cal OES (California Office of Emergency Services): State emergency management information
- Local Emergency Management: County-specific updates
- NOAA Tsunami Warning Centers: Technical details and forecasts
Frequently Asked Questions About California Tsunami Warnings
Is there a tsunami warning in California right now?
No, as of July 31, 2025, all official tsunami warnings and advisories have been lifted for California. However, coastal conditions may still be hazardous with strong rip currents expected to continue.
Where was the tsunami warning located in California?
The tsunami advisory initially covered the entire California coast, with specific alerts for Los Angeles, Orange, Ventura, Santa Barbara, San Luis Obispo, and Northern California counties including Humboldt and Del Norte.
Does California have a tsunami warning system?
Yes, California participates in the National Tsunami Warning System operated by NOAA. The state also has its own emergency alert systems through Cal OES and local emergency management agencies.
How long do tsunami warnings typically last in California?
Tsunami warnings can last from several hours to over a day, depending on the source earthquake and wave arrival times. The recent Russian earthquake warnings lasted approximately 12-18 hours for most California areas.
Where is the highest tsunami risk in California?
Northern California, particularly areas like Crescent City, faces the highest tsunami risk due to its geography and proximity to major Pacific earthquake zones. However, the entire California coast is considered at risk.
What should I do if there’s a tsunami warning in my area?
Immediately move inland and to higher ground, stay away from beaches and coastal waters, monitor official emergency channels, and follow local evacuation orders. Do not go to the coast to watch waves.
How are tsunami warnings different from tsunami watches?
A tsunami warning indicates imminent danger requiring immediate action, while a tsunami watch means a tsunami is possible and you should stay alert. An advisory indicates strong currents and dangerous conditions but not widespread flooding.
Can small tsunamis still be dangerous?
Yes, even small tsunami waves can create powerful currents, unexpected surges, and dangerous conditions for swimmers, surfers, and boaters. All tsunami advisories should be taken seriously.
How fast do tsunamis travel across the Pacific?
Tsunamis can travel across the Pacific Ocean at speeds of 400-500 mph in deep water, meaning waves from Russia can reach California in approximately 8-12 hours depending on the exact source location.
Are tsunami warnings automatically canceled?
No, tsunami warnings are carefully evaluated and canceled only when wave measurements and analysis confirm the threat has passed. Experts continuously monitor conditions before lifting alerts.
What’s the difference between tsunami waves and regular ocean waves?
Tsunami waves are much longer (wavelength), carry more energy, and can continue for hours. Unlike regular waves that affect only the surface, tsunamis involve the entire water column from surface to seafloor.
Should I evacuate for a tsunami advisory versus warning?
Evacuation is mandatory for tsunami warnings but may not be required for advisories. However, you should definitely stay away from beaches, harbors, and coastal waters during any tsunami alert.
