On May 19, 2026 at 23:27 UTC, a magnitude 3.0 shallow crustal earthquake struck 169 km SW of Nikolski, Alaska, at a depth of 11.1 km and coordinates 52.1030°, -170.9430°.

Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.
