On December 25, 2020 at 21:27 UTC, a magnitude 2.5 shallow crustal earthquake struck 2km ENE of Cabazon, CA, at a depth of 18.2 km and coordinates 33.9247°, -116.7693°.

Physical scale: An earthquake of magnitude 2.5 releases seismic energy equivalent to roughly 71.4 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 30 m — a useful intuition for the size of the slip patch on the fault.
