2026-09-05 00:22:03 UTC (4 days ago) · approx. 1:22 PM UTC-11 local
On September 5, 2026 at 00:22 UTC, a magnitude 3.2 intermediate depth earthquake struck 116 km WNW of Nikolski, Alaska, at a depth of 161.8 km and coordinates 53.3970°, -170.4340°.
Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 951 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 97 m — a useful intuition for the size of the slip patch on the fault.
