2025-02-07 23:30:48 UTC (2025-02-07) · approx. 12:30 PM UTC-11 local
On February 7, 2025 at 23:30 UTC, a magnitude 3.6 shallow crustal earthquake struck 25 km SW of Wales, Alaska, at a depth of 16.4 km and coordinates 65.4220°, -168.4121°.
Physical scale: An earthquake of magnitude 3.6 releases seismic energy equivalent to roughly 3.8 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 184 m — a useful intuition for the size of the slip patch on the fault.
