On August 16, 2024 at 22:32 UTC, a magnitude 3.7 intermediate depth earthquake struck 20 km ESE of King Cove, Alaska, at a depth of 103.1 km and coordinates 54.9933°, -162.0252°.

Physical scale: An earthquake of magnitude 3.7 releases seismic energy equivalent to roughly 5.4 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 215 m — a useful intuition for the size of the slip patch on the fault.
