Anchorage, AK – A magnitude 4.5 earthquake was recorded early Wednesday offshore of the Alaska Peninsula, striking about 81 kilometers east-southeast of Chignik, according to the Alaska Earthquake Center and the U.S. Geological Survey.
According to USGS data, the quake occurred at 4:17 a.m. AKST at a depth of roughly 28.6 kilometers, consistent with the region’s frequent subduction-zone seismic activity. No tsunami alert was issued, and no immediate damage reports have been released by local agencies.
The Alaska Earthquake Center reports that the seismic zone surrounding Chignik and the greater Alaska Peninsula remains one of the most active in North America. Wednesday’s event fits within an ongoing pattern of moderate offshore earthquakes that typically pose low risk to communities but remind residents of the area’s persistent tectonic movement.
USGS “Did You Feel It?” data showed at least one community-submitted report early Wednesday, though shaking is expected to have been light due to the offshore epicenter. The Alaska Earthquake Center continues to analyze the event to determine whether aftershocks or additional seismic activity may follow.
Chignik, located in the Lake and Peninsula Borough, sits roughly 450 miles southwest of Anchorage and is accustomed to routine earthquakes generated along the Alaska-Aleutian subduction zone. Officials emphasize that even moderate quakes like this serve as important reminders for residents to maintain updated emergency kits and communication plans.
More information and real-time seismic updates are available through the USGS Earthquake Hazard Program and the Alaska Earthquake Center.
