On April 14, 2025 at 20:52 UTC, a magnitude 3.2 intermediate depth earthquake struck 110 km ENE of Atka, Alaska, at a depth of 161.7 km and coordinates 52.5578°, -172.6842°.

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.
