On September 14, 2026 at 19:50 UTC, a magnitude 2.4 intermediate depth earthquake struck 17 km NNW of Nikiski, Alaska, at a depth of 73.4 km and coordinates 60.8350°, -151.4020°.

Physical scale: An earthquake of magnitude 2.4 releases seismic energy equivalent to roughly 60.0 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 27 m — a useful intuition for the size of the slip patch on the fault.
