A powerful 7.3‑magnitude earthquake struck off Alaska’s coast Wednesday, prompting an immediate tsunami warning for South Alaska and the Alaska Peninsula.
The USGS reported its epicenter was roughly 54 miles south of Sand Point at a shallow 20 km depth — conditions that raise tsunami fears.
The National Tsunami Warning Center confirmed a tsunami has occurred, cautioning coastal communities from Kennedy Entrance to Unimak Pass.
Though only these regions are at risk, residents are urged to evacuate low-lying areas and stay alert for updates.
Alaska, part of the seismic Pacific Ring of Fire, previously endured a deadly 9.2 quake in 1964—the strongest in North America, which unleashed a devastating tsunami.
While a 7.2 quake in July 2023 passed without major incident, the current event has revived emergency vigilance.
Authorities are working to assess impacts and ensure community safety as aftershocks and swelling waves remain a concern.
