On July 9, 2026 at 23:14 UTC, a magnitude 2.4 intermediate depth earthquake struck 10 km S of Tyonek, Alaska, at a depth of 85.4 km and coordinates 60.9720°, -151.1490°.

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.
