On November 26, 2020 at 21:45 UTC, a magnitude 2.3 shallow crustal earthquake struck 10km NW of Calipatria, CA, at a depth of 3.8 km and coordinates 33.1775°, -115.6043°.

Physical scale: An earthquake of magnitude 2.3 releases seismic energy equivalent to roughly 38.3 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 22 m — a useful intuition for the size of the slip patch on the fault.
