Hawaii earthquakes tsunami warning was issued on July 30, 2025, after a powerful 8.8-magnitude earthquake struck off Russia’s far eastern coast, sending waves surging across the Pacific. The Pacific Tsunami Warning Center initially put Hawaii on high alert, forecasting tsunami arrival just after 7 p.m. local time, with sirens echoing throughout the islands as officials urged residents in low-lying areas to seek higher ground immediately.
The first tsunami waves, though arriving at high tide, were reported at just under 5 feet in Hilo and 4 feet in Kahului, Maui. Authorities activated emergency shelters statewide and deployed Black Hawk helicopters in preparation for possible rescues. Airports temporarily shut down, with some flights to Hawaii from California turning back midair. Fortunately, reports so far confirm no major damage or casualties in Hawaii, though flooding has impacted several shoreline communities.
The tsunami warning was downgraded to an advisory as wave heights stabilized, but experts cautioned the threat could persist for hours. “A tsunami is not just one wave,” explained the National Tsunami Warning Center, “it’s a series of powerful waves over a long period”.
