Yakutat, AK – A moderate earthquake measuring magnitude 4.6 struck Southeast Alaska on Sunday morning, shaking areas north of Yakutat but posing no tsunami threat, according to federal officials.
According to the U.S. Geological Survey (USGS), the earthquake occurred at 9:51 a.m. Alaska Standard Time (AKST), with the epicenter located approximately 55 miles north of Yakutat and about 245 miles northwest of Juneau. The quake struck at a shallow depth of roughly 1 mile (10 kilometers), which can increase the likelihood of noticeable shaking near the epicenter.
The National Tsunami Warning Center in Palmer, Alaska, issued a Tsunami Information Statement shortly after the quake, confirming that there is no tsunami danger from this earthquake. Officials said no additional tsunami messages are expected unless new data becomes available.
USGS ShakeMap data indicated light shaking in sparsely populated areas, with no immediate reports of injuries or damage. The agency’s PAGER system rated the event GREEN, signaling a low likelihood of economic losses or fatalities.
Yakutat is located in a seismically active region near the boundary of the Pacific and North American tectonic plates, where earthquakes are relatively common. While Sunday’s quake was strong enough to be detected across the region, officials emphasized it does not meet the threshold for tsunami generation.
Residents who felt shaking are encouraged to submit reports through the USGS “Did You Feel It?” program, which helps scientists better understand ground motion and community impact.
The USGS said the earthquake has been reviewed and confirmed, and no aftershocks of concern have been reported as of Sunday afternoon.
