McCarthy, Alaska – A magnitude 3.3 earthquake was recorded 81 kilometers south of McCarthy on Thursday morning, registering at a shallow depth of 1.5 kilometers.
According to the Alaska Earthquake Center, the quake occurred at 16:33:14 UTC (7:33 a.m. Alaska Standard Time). The event was automatically reviewed and logged in the Alaska region.
Seismic data shows the epicenter was located at 60.706°N latitude and 143.114°W longitude in a remote area of the Copper River Census Area. The shallow depth may increase the likelihood of light shaking near the epicenter, though no damage or injuries were immediately reported.
A magnitude 3.3 earthquake is generally considered minor and typically does not cause structural damage. However, residents in nearby rural communities may have felt brief ground movement.
The Alaska Earthquake Center continues to monitor seismic activity across the state, which experiences frequent low-magnitude earthquakes due to its location along active tectonic boundaries.
While events of this size are common in Alaska, even minor quakes can be noticeable to residents, including remote workers, pilots and outdoor recreationists traveling through the region.
There were no tsunami advisories associated with this event.
