On July 24, 2023 at 20:38 UTC, a magnitude 2.5 shallow crustal earthquake struck 9km ESE of Cabazon, CA, at a depth of 13.4 km and coordinates 33.8937°, -116.6915°.

Physical scale: An earthquake of magnitude 2.5 releases seismic energy equivalent to roughly 94.1 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 34 m — a useful intuition for the size of the slip patch on the fault.
