Yakutat, Alaska – A magnitude 3.9 earthquake struck Friday evening north of Yakutat, Alaska, prompting light shaking reports across parts of the region, according to seismic data.
According to the Alaska Earthquake Center, the earthquake occurred at 4:59 p.m. local time (16:59 UTC) and was centered approximately 117 kilometers (73 miles) north of Yakutat. The quake originated at a shallow depth of about 5 kilometers, a factor that can increase the likelihood of shaking being felt near the epicenter.
Preliminary estimates indicate the earthquake reached a Modified Mercalli Intensity of IV, which is classified as light shaking. At this level, residents may notice rattling windows, vibrating walls, or brief movement of household objects, though damage is unlikely.
As of this update, no injuries or structural damage have been reported, and officials have not issued a tsunami warning or advisory. Earthquakes of this magnitude are common in southern Alaska, one of the most seismically active regions in the world due to ongoing tectonic plate movement along the Pacific Plate boundary.
The Alaska Earthquake Center encourages residents who felt the shaking to submit a “Did You Feel It?” report, which helps scientists better understand how earthquakes impact communities across remote and populated areas alike.
Emergency officials remind residents that while small earthquakes typically pose little risk, they can sometimes be followed by aftershocks, usually smaller in size.
Anyone living in the Yakutat area or traveling through southeastern Alaska is advised to remain aware but not alarmed.
