On May 25, 2026 at 05:20 UTC, a magnitude 3.1 intermediate depth earthquake struck 74 km E of King Salmon, Alaska, at a depth of 162.3 km and coordinates 58.6720°, -155.3820°.

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.
