On July 26, 2026 at 22:44 UTC, a magnitude 2.4 intermediate depth earthquake struck 31 km SSW of Petersville, Alaska, at a depth of 73.9 km and coordinates 62.2370°, -151.0050°.

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.
