On February 5, 2022 at 23:51 UTC, a magnitude 2.4 shallow crustal earthquake struck 3km NE of Dollar Point, CA, at a depth of 4.6 km and coordinates 39.2122°, -120.0750°.

Physical scale: An earthquake of magnitude 2.4 releases seismic energy equivalent to roughly 56.0 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 26 m — a useful intuition for the size of the slip patch on the fault.
