2026-07-14 13:57:29 UTC (1 day ago) · approx. 2:57 AM UTC-11 local
On July 14, 2026 at 13:57 UTC, a magnitude 3.0 shallow crustal earthquake struck 172 km SW of Nikolski, Alaska, at a depth of 25.0 km and coordinates 52.0360°, -170.9210°.
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.
