On May 8, 2025 at 21:56 UTC, a magnitude 3.2 intermediate depth earthquake struck 47 km NNE of Chase, Alaska, at a depth of 76.4 km and coordinates 62.8244°, -149.6547°.

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.
