Tsunami Warning Trends in Alaska Following Powerful Earthquake
On July 16, 2025, a powerful magnitude 7.3 earthquake struck off the coast of the Alaska Peninsula, sparking widespread concern and triggering a tsunami warning that quickly became the top trending search term across the state.
The quake, centered in the ocean southeast of Sand Point, Alaska, occurred in a seismically active region known for producing large earthquakes. As a result, the National Tsunami Warning Center immediately issued warnings for coastal areas between Kennedy Entrance and Unimak Pass, advising residents to move inland or to higher ground.
Communities such as Kodiak, Homer, Unalaska, and Sand Point went on high alert, with emergency services activating evacuation protocols. Local residents turned to the internet in huge numbers, searching for updates with terms like “tsunami warning Alaska,” “how big will the wave be,” and “evacuation map.”
However, about an hour after the earthquake, data from ocean buoys showed only a minor sea level change of around 0.2 feet (3 inches) near Sand Point. The tsunami warning was quickly downgraded to an advisory and later canceled entirely.
Despite the minimal wave impact, the incident served as a stark reminder of Alaska’s vulnerability to natural disasters and the importance of rapid information dissemination. Fortunately, there were no reports of injuries or major damage.
