Is there a tsunami warning today?
As of the latest data from official sources, the answer is no. NOAA’s Tsunami Program directs users to the U.S. Tsunami Warning System, which currently shows zero active warnings, advisories, watches, or threats. The National Weather Service confirms its tsunami warning centers are staffed 24 hours a day, 7 days a week, ready to issue alerts at any moment.
Is there a tsunami happening?
No. No tsunami is currently occurring anywhere in the world. The latest warnings issued after the July 5, 2026 earthquake were cancelled without any wave impact.
What does a tsunami warning mean?
- Tsunami warning — issued when a tsunami with potential for widespread inundation is imminent, expected, or occurring (UNESCO-IOC Tsunami Information Center)
- Tsunami watch — issued when an event may later impact the watch area; may be upgraded or canceled
- Tsunami information statement — indicates no threat of a destructive tsunami in most cases
The UNESCO-IOC Tsunami Information Center notes that each member state is responsible for issuing warnings to its own citizens through National Tsunami Warning Centres or designated authorities. So even if the Pacific Tsunami Warning Center detects a threat, it’s local agencies that push the alert to your phone.
How to check live tsunami alerts
- Visit Tsunami.gov — the official U.S. alert dashboard updated in real time
- Subscribe to receive messages directly from NOAA’s warning centers via Tsunami.gov (National Weather Service)
- In Washington State, alerts are broadcast through local radio, TV, marine radio, Wireless Emergency Alerts, NOAA Weather Radio, outdoor sirens, and text messages (Washington State Military Department)
The global warning system is designed to buy minutes — not hours. For residents of the Pacific Rim, those minutes are the difference between reaching high ground and being caught in the surge. The current quiet period is the best time to check your local alert channels and know your evacuation route.
The implication: the system is working, but the absence of warnings does not mean zero risk.
What happened to the tsunami warning from the Russia earthquake?
The warning was cancelled after no tsunami materialized. The 8.8 earthquake off Russia’s Kamchatka Peninsula triggered advisories for the Pacific, but all were lifted within hours. No waves were reported.
Which countries were hit by the tsunami?
No recent tsunami has impacted land areas. The warnings issued after the July 5, 2026 8.8 earthquake off Russia were later cancelled, with no reported wave damage to any coastline. Historically, the Pacific and Indian Oceans have seen the deadliest events.
Was Canada affected?
- July 2026: No tsunami waves reached Canadian shores; advisories for the West Coast were cancelled
- Historical: Canada’s Pacific coast has experienced tsunamis, most notably the 1964 Alaska earthquake generated waves that struck British Columbia, causing damage in Port Alberni and other communities
- Atlantic risk: Canada’s east coast faces lower tsunami threat, though distant events (e.g., 1755 Lisbon) have produced measurable waves
According to UNESCO-IOC Tsunami Information Center, the Pacific Tsunami Warning Center serves as the international warning center for the Pacific, covering Canada’s west coast among many other nations. The UWI Seismic Research Centre notes that for the Caribbean, PTWC sends bulletins to Tsunami Warning Focal Points, and communicating the warning to the public is the responsibility of the national disaster management agency in each country.
Was Greece affected?
- Greece and the broader Mediterranean have experienced tsunamis historically, most notably the 365 AD Crete earthquake and tsunami that devastated Alexandria
- No current tsunami warning for Greece or the Mediterranean region
- The Mediterranean has lower tsunamigenic potential than the Pacific but is not immune
The Atlantic and Mediterranean basins are not tsunami-free — they’re just less frequently tested. The 1755 Lisbon earthquake produced a transatlantic tsunami that reached the Caribbean, and the 365 AD Crete event flooded thousands of square kilometers of coastline. Low probability does not mean zero probability.
The takeaway: no land was hit, but the system’s response shows readiness.
How high was the latest tsunami?
No wave heights have been reported for the 2026 events because no tsunami materialized. The most recent significant tsunami with measured wave heights remains the 2011 Tohoku tsunami in Japan, which reached approximately 40 meters (130 feet) in some coastal areas, according to historical records.
What is the typical height of a tsunami?
- In deep ocean: tsunami waves are typically less than 1 meter high and travel at speeds up to 800 km/h (500 mph)
- As they approach shore: wave height increases dramatically — a phenomenon called “shoaling” — and can exceed 30 meters
- The 2004 Indian Ocean tsunami reached heights of 30 meters in some locations, claiming ~230,000 lives across 14 countries
How are tsunami heights measured?
- Deep-ocean buoys (DART stations) measure pressure changes to detect tsunami waves before they reach shore
- Coastal tide gauges record wave height as the tsunami arrives
- The CTBTO says its hydroacoustic and seismic data can provide up to three minutes of lead time for tsunami alerts, transmitted in near real-time to national tsunami warning centers
The implication: three minutes of additional lead time, multiplied across thousands of coastal residents, can mean the difference between orderly evacuation and chaos. Every second counts.
What country is most at risk of tsunamis?
Japan, Indonesia, Chile, the Philippines, and the United States (Hawaii and the West Coast) face the highest risk due to their location along the Pacific Ring of Fire, where tectonic plate boundaries produce frequent large earthquakes and volcanic activity.
Why is Japan highly vulnerable?
- Japan sits at the convergence of four tectonic plates (Pacific, Philippine Sea, Eurasian, and North American)
- The country has experienced some of the most destructive tsunamis in recorded history, including the 2011 Tohoku event that killed ~18,000 people
- Japan operates one of the world’s most advanced tsunami warning systems, with dense seismic networks and coastal defenses
Are Atlantic countries at risk?
- Atlantic tsunami risk is lower but real: the 1755 Lisbon earthquake generated a tsunami that struck Portugal, Spain, Morocco, and reached the Caribbean
- A potential landslide from the Cumbre Vieja volcano in the Canary Islands has been modeled as a scenario for a large Atlantic tsunami, though this remains unconfirmed and contested in scientific literature
- The UNESCO-IOC Tsunami Information Center notes that the Pacific Tsunami Warning Center serves as the international warning center for the Pacific, while the Atlantic and Mediterranean have their own regional warning systems
What this means: risk is concentrated in the Pacific, but Atlantic nations should not ignore preparedness.
Is Ireland at risk of a tsunami?
Ireland and the UK have very low tsunamigenic risk. The last confirmed tsunami to affect the British Isles was the 1755 Lisbon earthquake, which generated small waves — less than 1 meter — along the south coast of England and Ireland. No tsunami warning has ever been issued for Ireland in the modern warning system era.
Could the UK be hit by a tsunami?
- The UK’s position on the passive margin of the Atlantic means it is not near major subduction zones that generate large tsunamis
- Historical tsunamis affecting the UK include the 1755 Lisbon event (small waves) and a 1607 event in the Bristol Channel, though the latter is debated as possibly a storm surge rather than a tsunami
- Earthquake hazard in the UK is low — the British Geological Survey describes the region as having “low to moderate” seismicity
When was the last time a tsunami hit Ireland?
- The 1755 Lisbon earthquake generated waves of approximately 1 meter along Ireland’s south coast
- A 1761 earthquake in Portugal also produced small waves in Ireland
- No tsunamis have been recorded in Irish waters in the modern era (post-1900)
Is it possible for Ireland to have an earthquake?
Yes, but the risk is low. The British Geological Survey classifies Ireland’s seismicity as “low to moderate”. Most earthquakes are small and rarely felt. However, a large earthquake in the Atlantic could generate distant waves.
The catch: low risk does not mean no risk. The potential for a Canary Islands landslide scenario, while speculative, would affect the entire Atlantic basin, including Ireland and the UK. Scientists continue to monitor the Cumbre Vieja volcano for signs of instability. For more on coastal safety, see our 90 Mile Beach tides guide.
Recent timeline: tsunami events and warnings
- July 5, 2026 — 8.8 earthquake off Russia’s Kamchatka Peninsula triggers tsunami warnings for the Pacific; advisories issued for Alaska and the U.S. West Coast; later cancelled with no impact (National Weather Service)
- 2024 — No major tsunamis recorded; warning systems upgraded globally including CTBTO integration (CTBTO)
- 2011 — Tohoku earthquake and tsunami (Japan) — 40m waves, ~18,000 deaths, Fukushima nuclear disaster (NOAA Tsunami Program)
- 2004 — Indian Ocean tsunami — 230,000 deaths across 14 countries, leading to major improvements in global warning infrastructure (UNESCO-IOC Tsunami Information Center)
Why this matters: the gap between 2004 and 2011 was just seven years. The gap between 2011 and today is fifteen years and counting. Preparedness systems have improved dramatically, but the geological clock keeps ticking.
Confirmed facts vs. what remains unclear
Confirmed facts
- No tsunami warning is in effect as of July 5, 2026 (NOAA Tsunami Program)
- The 8.8 earthquake off Kamchatka triggered warnings that were later cancelled
- NOAA’s warning centers are staffed 24/7 (National Weather Service)
- Each country is responsible for issuing warnings to its own citizens (UNESCO-IOC Tsunami Information Center)
What’s unclear
- Whether the Russia earthquake will produce a tsunami after the initial warning cancellation (National Weather Service)
- Potential for future Atlantic tsunamis from a Canary Islands landslide — remains a scientific scenario, not a confirmed prediction (UNESCO-IOC Tsunami Information Center)
- Exact timing of the next major Pacific subduction zone earthquake
- Whether the current quiet period indicates a low probability of a tsunami in the near future, or merely a temporary lull in seismic activity
The distinction: confirmed facts come from official systems; uncertainties remain about future events.
What experts say
“There is No Tsunami Warning, Advisory, Watch, or Threat in effect.”
— U.S. Tsunami Warning Center, official status page
“8.8 earthquake off Russia prompts tsunami warnings for parts of Pacific.”
— CBS News, established editorial outlet covering the July 2026 event
“The data can provide up to three minutes of lead time for tsunami alerts.”
— CTBTO, international organization transmitting near real-time data to national warning centers
“Communicating the warning to the public is the responsibility of the national disaster management agency in each Caribbean country.”
— UWI Seismic Research Centre, regional earthquake and tsunami monitoring authority
For residents of the Pacific Rim, the choice is clear: know your evacuation route, test your alert channels, and treat every warning as a real event until authorities confirm otherwise. For those in the Atlantic basin, the risk is lower but the same principle applies — awareness today beats panic tomorrow.

Frequently asked questions
What should I do if a tsunami warning is issued?
Move immediately to higher ground or inland, away from the coast. Follow evacuation routes marked by local authorities. Do not wait for a second wave — tsunamis are a series of waves, and the first may not be the largest. Tune into NOAA Weather Radio, local TV, or radio for updates. The Washington State Military Department notes that alerts may be broadcast through sirens, Wireless Emergency Alerts, and text messages.
How are tsunami warnings issued?
Tsunami warnings are issued by national tsunami warning centers after detecting a large earthquake or other tsunami-generating event. The Pacific Tsunami Warning Center serves as the international warning center for the Pacific, sending bulletins to member states who then issue local alerts. The CTBTO provides additional seismic and hydroacoustic data to improve speed and accuracy.
Can a tsunami happen in the Atlantic Ocean?
Yes, though less frequently than in the Pacific. The most notable Atlantic tsunami was the 1755 Lisbon earthquake event, which generated waves that struck Portugal, Spain, Morocco, and reached the Caribbean. A potential Canary Islands landslide scenario has been modeled but remains unconfirmed. The Atlantic has regional warning systems coordinated through UNESCO-IOC.
What is the difference between a tsunami warning and an advisory?
According to UNESCO-IOC Tsunami Information Center: a warning means a tsunami with widespread inundation is imminent or occurring; a watch means an event may later impact the area; an advisory indicates strong currents or dangerous waves are possible but widespread inundation is not expected; and an information statement typically means no threat.
How fast do tsunami waves travel?
Tsunami waves travel at speeds up to 800 km/h (500 mph) in deep ocean — roughly the speed of a jet aircraft. As they approach shallow water, speed decreases dramatically while wave height increases. This speed is why detection systems like the CTBTO’s network are critical: every minute of additional warning time allows coastal communities to move people inland.
Are cruise ships safe from tsunamis?
In deep ocean, tsunami waves are barely noticeable to ships because they are very long and low. The danger to cruise ships occurs in port or near shore, where a tsunami can cause rapid water level changes, strong currents, and damage to harbor infrastructure. Port authorities typically move ships to open water if a tsunami warning is issued.
Do tsunamis affect the Mediterranean?
Yes. The Mediterranean has a history of tsunamis, most notably the 365 AD Crete earthquake and tsunami that devastated coastal cities from Greece to Egypt. The 1908 Messina earthquake in Italy also generated a tsunami. Greece, Italy, and Turkey face the highest risk in the region. The Mediterranean is covered by the UNESCO-IOC Intergovernmental Coordination Group for tsunami early warning.
What is the most recent tsunami in Europe?
The most recent significant tsunami in Europe was the 2003 Boumerdès earthquake in Algeria, which generated a small tsunami that affected the Balearic Islands and the French and Spanish coasts. The most destructive European tsunami in modern history was the 1908 Messina earthquake tsunami in Italy, which killed an estimated 80,000 people.
