2025-11-02 17:11:59 UTC (2025-11-02) · approx. 6:11 AM UTC-11 local
On November 2, 2025 at 17:11 UTC, a magnitude 3.8 intermediate depth earthquake struck 36 km NNE of False Pass, Alaska, at a depth of 189.1 km and coordinates 55.1750°, -163.2969°.
Physical scale: An earthquake of magnitude 3.8 releases seismic energy equivalent to roughly 7.6 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 252 m — a useful intuition for the size of the slip patch on the fault.
