On February 14, 2023 at 17:40 UTC, a magnitude 3.6 shallow crustal earthquake struck 164 km W of Crescent City, California, at a depth of 19.6 km and coordinates 41.5071°, -126.1444°.

Physical scale: An earthquake of magnitude 3.6 releases seismic energy equivalent to roughly 3.8 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 184 m — a useful intuition for the size of the slip patch on the fault.
