False Pass, Alaska – A magnitude 4.0 earthquake struck 207 kilometers south of False Pass on Sunday morning, according to the U.S. Geological Survey.
The quake occurred at 9:12 a.m. UTC at a depth of 10.0 kilometers, USGS data shows. The epicenter was located offshore in the North Pacific south of the Aleutian Islands chain.
The event was reviewed by the USGS National Earthquake Information Center. No tsunami warning was issued in connection with the quake, and there were no immediate reports of damage or injuries.
A magnitude 4.0 earthquake is generally considered light and is often felt near the epicenter but typically does not cause significant structural damage. Given the offshore location and distance from populated areas, impacts are expected to be minimal.
False Pass, located in Aleutians East Borough, is a small fishing community along the eastern Aleutian Islands. Offshore seismic activity is common in this region due to tectonic movement along the Pacific Plate boundary.
The USGS encourages residents who felt shaking to submit reports through its “Did You Feel It?” system to help refine impact data.
While this event poses little threat to infrastructure, it serves as a reminder of Alaska’s high seismic activity. Students and workers in coastal communities are often advised to remain aware of earthquake preparedness protocols.
