Ivanof Bay, Alaska – A shallow earthquake struck just after 4:05 a.m. Sunday near the Bristol Bay region, registering a magnitude 3.1 and occurring only 5 kilometers below the surface, a depth that can allow shaking to be felt close to the epicenter.
According to the Alaska Earthquake Center, the tremor hit 32 kilometers west-northwest of Ivanof Bay at 12:05:32 UTC and was automatically recorded with a low intensity rating. No immediate reports of damage or infrastructure disruption have been confirmed, and early data suggests minimal impact to nearby communities and coastal operations.
The quake occurred in a seismically active stretch of southern Alaska, though events of this size rarely cause structural concerns. Fishing vessels, remote lodges, and small settlements scattered across the Alaska Peninsula may have experienced brief, light shaking, particularly in areas closest to the epicenter.
While no tsunami threat was issued, officials remind residents and workers in the region to remain aware of aftershocks, even though the likelihood remains low with a quake of this magnitude. Securing loose items and reviewing emergency plans remains standard guidance across earthquake-prone areas.
Seismic monitoring continues across the region, and additional updates will be issued if activity increases through Sunday morning.
