On May 19, 2026 at 10:08 UTC, a magnitude 3.2 intermediate depth earthquake struck 57 km N of Petersville, Alaska, at a depth of 116.5 km and coordinates 63.0080°, -150.7330°.

Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 951 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 97 m — a useful intuition for the size of the slip patch on the fault.
