On March 14, 2026 at 18:14 UTC, a magnitude 3.1 intermediate depth earthquake struck 58 km WNW of Anchor Point, Alaska, at a depth of 109.2 km and coordinates 59.9450°, -152.8260°.

Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 674 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 83 m — a useful intuition for the size of the slip patch on the fault.
