On September 4, 2026 at 23:23 UTC, a magnitude 2.6 intermediate depth earthquake struck 7 km WNW of Nikiski, Alaska, at a depth of 74.9 km and coordinates 60.7250°, -151.4020°.

Physical scale: An earthquake of magnitude 2.6 releases seismic energy equivalent to roughly 120 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 37 m — a useful intuition for the size of the slip patch on the fault.
