2026-09-02 19:13:54 UTC (2026-09-02) · approx. 9:13 AM UTC-10 local
On September 2, 2026 at 19:13 UTC, a magnitude 3.0 shallow crustal earthquake struck 86 km W of Akhiok, Alaska, at a depth of 55.6 km and coordinates 56.8350°, -155.5770°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.
