Washington – July 17, 2025
A 7.3-magnitude earthquake struck off the coast of Alaska on Wednesday, according to the U.S. Geological Survey (USGS). The seismic activity prompted a temporary tsunami warning, which was later downgraded and eventually canceled.
The earthquake occurred at 12:37 PM local time (20:37 GMT) and was centered approximately 54 miles (87 kilometers) south of Sand Point island town. The USGS reported a depth of 12.5 miles (20 kilometers) beneath the surface.
In the immediate aftermath, authorities issued a tsunami warning for parts of southern Alaska and the Alaska Peninsula. However, after further analysis and no significant wave activity, the alert was first downgraded to an advisory and later completely withdrawn.
No major damage or casualties have been reported so far. Alaska, part of the seismically active Pacific Ring of Fire, frequently experiences earthquakes of varying magnitudes.
