On May 27, 2025 at 16:46 UTC, a magnitude 3.2 intermediate depth earthquake struck 53 km W of Nanwalek, Alaska, at a depth of 71.3 km and coordinates 59.3511°, -152.8639°.

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.
