On September 3, 2026 at 23:21 UTC, a magnitude 3.4 intermediate depth earthquake struck 57 km W of Anchor Point, Alaska, at a depth of 112.7 km and coordinates 59.7700°, -152.8590°.
Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 1.9 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 134 m — a useful intuition for the size of the slip patch on the fault.
