A major earthquake on July 16, 2025, has once again pushed Alaska’s coastal residents to confront the dangers associated with the alaska tsunami 2025 event. The quake, which struck just offshore near Sand Point, set off alarms and warnings across the southern coastline, triggering a rapid, large-scale emergency response.
Earthquake and Tsunami Warning Shake Alaska Peninsula
On Wednesday afternoon, a magnitude 7.3 earthquake rattled communities like Sand Point, Cold Bay, and Kodiak. The epicenter was recorded about 55 miles south of Sand Point, at a depth of 12–22 miles beneath the Pacific Ocean. The seismic activity was strong enough to cause items to fall from shelves and left residents deeply unsettled, though no major damage was reported.
The U.S. Tsunami Warning Center issued an immediate tsunami warning for a 700-mile stretch of Alaska’s southern coast, from Kennedy Entrance (near Homer) to Unimak Pass. Sirens wailed in affected cities, with officials urging residents to evacuate low-lying areas and head for higher ground. Shelters were quickly opened in cities like Kodiak, where emergency protocols moved into action.
