A powerful Alaska earthquake struck off the state’s southern coast on Wednesday, sparking a short-lived tsunami advisory. The 7.3-magnitude quake occurred at 12:37 p.m. local time, according to the U.S. Geological Survey (USGS).
The earthquake’s epicenter was located about 54 miles south of Sand Point, a small island town. It had a depth of 20.1 kilometers. This region lies along the Pacific Ring of Fire, known for frequent seismic activity.
Authorities initially issued a tsunami warning for coastal areas, which was later downgraded to an advisory. Two hours after the quake, the National Tsunami Warning Center (NTWC) officially canceled the advisory.
Communities affected by the alert stretched from Kennedy Entrance to Unimak Pass. These include parts of Alaska’s southern coast tsunami warning zone, covering over 700 miles of coastline.
A small tsunami wave was recorded at Sand Point, measuring just 0.2 feet (about 6.1 centimeters). While minor, it prompted swift action from local emergency services.
The NTWC urged residents to avoid beaches, harbors, and other coastal areas during the advisory. People were told not to return until authorities confirmed it was safe.
The Alaska tsunami warning issued after 7.3-magnitude earthquake caused concern but no significant damage has been reported so far. However, the USGS recorded more than a dozen aftershocks, the largest reaching a magnitude of 5.2.
This event is a reminder of the region’s vulnerability to seismic events. Just last year, a similar quake struck nearby, though it also resulted in no major damage.
Officials continue to monitor for aftershocks. Residents are advised to stay updated through local emergency channels and to follow all safety instructions.
