A 5.4-magnitude earthquake hit Alaska early Thursday (October 30), according to the U.S. Geological Survey (USGS).
Officials said the quake’s epicenter was about 30 miles east-southeast of Fox River at a depth of roughly 23.6 kilometers (15 miles). The USGS received nearly 2,000 reports from people who felt the shaking shortly after the tremor occurred.
A 2.6-magnitude aftershock was later recorded near Fox River the same day.
No tsunami warning, advisory, or watch was issued following the quake. The National Weather Service’s U.S. Tsunami Warning System confirmed, “There is no tsunami danger from this earthquake,” adding that further updates would come from the USGS or the appropriate regional seismic network.
Alaska remains one of the most seismically active regions in the United States, with 19 earthquakes reported in the past 24 hours, 103 in the past week, 484 in the past month, and more than 6,000 over the past year.
The state’s largest quake in 2025 so far was a 7.3-magnitude earthquake near Sand Fork.
