US EditionAnchorage Shaken as 5.4 Earthquake Strikes Southern Alaska
The 5.4 magnitude quake struck 110 miles south of Anchorage at 15 miles depth with no damage or tsunami risk, officials said.
- On Thursday morning, a magnitude-5.4 earthquake struck the Aleutian region of southern Alaska just after 9:30 a.m., prompting residents to report shaking.
- Geologists note Alaska is one of the most seismically active regions where earthquakes occur as stress along faults releases energy producing seismic waves.
- The USGS located the epicenter about 50 miles south-southwest of Nikolski, and seismologists reported it originated roughly 24 miles below the surface, with shaking felt through the Kenai Peninsula.
- NOAA's National Tsunami Warning Center and local emergency agencies said there is no tsunami risk and reported no significant damage, urging residents in affected areas to remain alert for aftershocks.
- Because the Aleutian arc is a subduction zone, this breaking news ties to plate motion where the Pacific Plate slides beneath the North American Plate, with updates on FOXWeather.com.
