On November 15, 2023 at 20:13 UTC, a magnitude 3.1 shallow crustal earthquake struck 1 km ESE of King Cove, Alaska, at a depth of 3.1 km and coordinates 55.0579°, -162.2949°.

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.
