Port Graham, Alaska – A magnitude 3.0 earthquake rattled part of the Kenai Peninsula early Saturday, striking just offshore and sending a brief jolt across communities along Kachemak Bay.
According to the U.S. Geological Survey, the quake hit at 15:04 UTC Saturday at a depth of nearly 54 kilometers, centered about 12 kilometers south-southwest of Port Graham. No damage or injuries have been reported, and there were no immediate disruptions to utilities or transportation.
Residents in Port Graham, Nanwalek and coastal sections of the lower peninsula may have felt light shaking, though early “Did You Feel It?” responses show no formal reports submitted. Local emergency managers noted that quakes of this size are common in the region’s active tectonic zone, where deep, intermediate-depth events occur regularly along the Aleutian subduction interface.
Fishermen and boat operators working off the southern Kenai coast are encouraged to monitor marine communications channels, though Saturday’s quake posed no tsunami threat. Minor aftershocks remain possible through the day, but none have been detected so far.
Seismic agencies will continue to review data, and updates will follow if additional activity develops.
