On October 21, 2026 at 12:58 UTC, a magnitude 3.2 shallow crustal earthquake struck 240 km SSE of False Pass, Alaska, at a depth of 21.3 km and coordinates 52.8410°, -162.0760°.

Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 951 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 97 m — a useful intuition for the size of the slip patch on the fault.
