When Will the Hawaii Tsunami Hit?
Hawaii was under a tsunami warning due to an 8.8-magnitude earthquake off Russia’s Kamchatka Peninsula. The Pacific Tsunami Warning Center estimated the first tsunami waves would arrive around 7:17 PM Hawaii Standard Time.
However, the tsunami warning for Hawaii was later downgraded to an advisory, according to the National Weather Service, as of 10:39 PM HST. The Pacific Tsunami Warning Center (PTWC) indicated that Hawaii is likely past the peak threat, with no major tsunami impacts anticipated greater than those already observed.
The initial waves impacted the Hawaii coast around 7:30 PM local time. While a tsunami advisory remains in effect for Hawaii, indicating potential for strong currents and dangerous waves, major destructive waves are not expected at this time.
Recent Tsunami in Hawaii
The most recent tsunami to affect Hawaii occurred on July 29, 2025, following an 8.8-magnitude earthquake off Russia’s Kamchatka Peninsula. The first waves reached Hawaii around 7:17 p.m. local time (HST), with initial wave heights detected at approximately 7:30 p.m. HST.
The Pacific Tsunami Warning Center (PTWC) issued a tsunami warning, which was downgraded to an advisory by 10:40 p.m. HST the same day. As of now, the primary threat has passed, with no significant damage reported.
Coastal areas may still experience minor waves and strong currents, and residents are advised to avoid beaches until authorities confirm safety.
When Will the Next Tsunami Happen?
Forecasting the exact timing of the next tsunami remains beyond our current capabilities, as these events stem from unpredictable natural phenomena such as earthquakes, volcanic eruptions, or landslides. Nonetheless, scientific research has identified several high-risk areas where tsunamis are more likely in the coming decades:
- Mediterranean: Experts predict a 100% chance of a tsunami exceeding one meter within the next 30 years, possibly sparked by an earthquake in the Alboran Sea.
- Japan (Nankai Trough): There’s an 80% likelihood of a magnitude 9 earthquake occurring within 30 years, which could unleash waves as high as 100 feet.
- Cascadia Subduction Zone (U.S.): A 15% probability exists for a magnitude 8.0+ earthquake within 50 years, potentially affecting the Pacific Northwest and Hawaii.
- New Zealand: Positioned along the Ring of Fire, this region faces a 1-in-500-year risk of a significant tsunami.
Be cautious of unverified social media claims, such as predictions of a 2026 tsunami following recent Japan Sea quakes, which lack credible scientific backing. Learn more about regional risks in the When Will the Next Tsunami Hit Hawaii? and Tsunami Warning Today: Is There a Threat? sections.
When Will the Next Tsunami Hit Hawaii?
No specific date can be predicted for the next Hawaii tsunami. The recent event on July 29, 2025, was a result of the Kamchatka earthquake, and current data suggests no immediate follow-up tsunami. Historical data shows Hawaii’s vulnerability due to its Pacific location, with past events like the 1946 Aleutian Islands tsunami causing significant impact. Monitoring by the PTWC provides real-time alerts, and residents should rely on official warnings.
When Will the Next Tsunami Happen in Australia?
Australia, though less prone than some regions, faces a genuine tsunami risk due to its proximity to tectonic boundaries. The 2004 Indian Ocean tsunami brought waves up to 7.9 meters to Western Australia, serving as a stark reminder. Scientists estimate a 40% chance of a significant tsunami (over 0.5 meters) within the next 50 years, likely originating from the Java Trench. While no specific timeline can be set, the Australian Tsunami Warning System continuously tracks seismic activity to provide timely alerts. Discover more about global tsunami risks in the When Will the Next Tsunami Happen? section.
When Will the Next Tsunami Happen in Thailand?
Thailand continues to be vulnerable following the catastrophic 2004 Indian Ocean tsunami, which claimed over 5,000 lives. The seismic activity in the Andaman and Nicobar region suggests a future tsunami is possible, with a 30-40% probability of a significant event within 50 years. The Thai Meteorological Department relies on Indian Ocean seismic data to issue warnings, though predicting the exact timing remains challenging.
