On October 22, 2026 at 07:00 UTC, a magnitude 2.9 shallow crustal earthquake struck 51 km N of Sutton-Alpine, Alaska, at a depth of 16.8 km and coordinates 62.2370°, -148.8170°.

Physical scale: An earthquake of magnitude 2.9 releases seismic energy equivalent to roughly 338 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 60 m — a useful intuition for the size of the slip patch on the fault.
