An magnitude 3.9 earthquake occurred 114 km SSE of Prudhoe Bay, Alaska on Sep 5, 2026 at 23:15 UTC. The epicenter was at a depth of 16 km — a shallow earthquake. Shallow quakes concentrate their energy near the surface, so they tend to produce stronger shaking close to the epicenter.

What this magnitude typically means
Minor earthquakes are often felt close to the epicenter but almost never cause damage. Whether you feel one at all depends on how near and how shallow it is. Tremor does not compute a single local shaking figure here, because how strong a quake feels at any address depends on distance, depth and local geology — open the interactive globe to explore the ShakeMap and estimated intensity.
