On January 13, 2024 at 23:14 UTC, a magnitude 3.9 shallow crustal earthquake struck 135 km ESE of Nikolski, Alaska, at a depth of 10.0 km and coordinates 52.5397°, -166.9606°.

Physical scale: An earthquake of magnitude 3.9 releases seismic energy equivalent to roughly 11 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 296 m — a useful intuition for the size of the slip patch on the fault.
