On November 22, 2024 at 13:52 UTC, a magnitude 3.1 shallow crustal earthquake struck 100 km SSE of Akutan, Alaska, at a depth of 35.0 km and coordinates 53.3510°, -165.0193°.

Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 674 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 83 m — a useful intuition for the size of the slip patch on the fault.
