On November 6, 2024 at 21:35 UTC, a magnitude 3.0 shallow crustal earthquake struck 27 km NNE of Atka, Alaska, at a depth of 3.2 km and coordinates 52.4362°, -174.1030°.

Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.
