On May 31, 2022 at 23:53 UTC, a magnitude 3.1 shallow crustal earthquake struck 20km NNE of Ridgecrest, CA, at a depth of 5.9 km and coordinates 35.7945°, -117.6253°.

Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 629 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 80 m — a useful intuition for the size of the slip patch on the fault.
