On June 23, 2026 at 21:19 UTC, a magnitude 2.9 intermediate depth earthquake struck 24 km SW of Petersville, Alaska, at a depth of 92.9 km and coordinates 62.3700°, -151.1570°.

Physical scale: An earthquake of magnitude 2.9 releases seismic energy equivalent to roughly 338 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 60 m — a useful intuition for the size of the slip patch on the fault.
