On August 6, 2024 at 20:53 UTC, a magnitude 3.7 intermediate depth earthquake struck 55 km NE of Nikolski, Alaska, at a depth of 78.7 km and coordinates 53.2205°, -168.1861°.

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.
