On October 14, 2024 at 17:41 UTC, a magnitude 3.2 shallow crustal earthquake struck 115 km SSW of Atka, Alaska, at a depth of 35.0 km and coordinates 51.2717°, -174.9648°.

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.
