Powerful Earthquake Shakes Alaska’s Largest City
A significant 5.4 magnitude earthquake struck near Alaska’s coast on Thursday, sending tremors through Anchorage and affecting approximately 300,000 residents. The US Geological Survey recorded the quake at 9:30 AM local time, with over 2,000 people reporting the shaking.
Key Takeaways
- Magnitude 5.4 earthquake struck 110 miles south of Anchorage
- Over 2,000 people reported feeling the tremors
- High probability of aftershocks in coming week
- Comes weeks after devastating typhoon remnants battered coastal villages
Earthquake Details and Aftershock Forecast
The earthquake originated in a remote coastal area about 29 miles southeast of Fox River. The USGS detected a smaller 2.6 magnitude tremor approximately five minutes later. Seismologists predict an 87% chance of magnitude 3 or higher aftershocks, 47% for magnitude 4 or higher, and 12% for another magnitude 5 earthquake within the next week.
Seismic Activity in the Aleutian Arc
The quake occurred along the eastern Aleutian arc, where the Pacific Plate slides beneath the North American Plate, creating intense seismic activity. This region has a history of devastating earthquakes, including the 1964 magnitude 9.2 Prince William Sound earthquake – the second largest ever recorded – which caused widespread damage in Anchorage and triggered a Pacific-wide tsunami.
One local shared on X: ‘Good-sized earthquake here in Alaska. I hear it was around Fritz Creek, so I felt the rolling and a good-sized crack and final shake.’
Recent Typhoon Impacts Compound Emergency
The earthquake comes weeks after Alaska experienced record storm surges from typhoon remnants that battered northwestern coastal communities. Hundreds of residents were airlifted to safety in one of the state’s most significant evacuation operations.
Coastal villages of Kipnuk and Kwigillingok suffered extensive damage, with 121 homes destroyed in Kipnuk alone. Tragically, Ella Mae Kashatok, 67, was found dead in Kwigillingok, while the search for two missing men was called off after their home was swept out to sea.
Recovery efforts continue across affected villages, with damage to critical infrastructure including water, sewer and well systems in multiple communities. Emergency management officials are working to relocate evacuees from congregate shelters to more permanent housing solutions.
