On July 9, 2026 at 10:09 UTC, a magnitude 2.5 intermediate depth earthquake struck 50 km WNW of Ninilchik, Alaska, at a depth of 93.5 km and coordinates 60.1820°, -152.5420°.

Physical scale: An earthquake of magnitude 2.5 releases seismic energy equivalent to roughly 84.8 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 32 m — a useful intuition for the size of the slip patch on the fault.
