On October 26, 2024 at 19:24 UTC, a magnitude 3.0 intermediate depth earthquake struck 22 km SE of King Cove, Alaska, at a depth of 77.4 km and coordinates 54.9044°, -162.0875°.

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.
