On July 15, 2024 at 22:15 UTC, a magnitude 2.3 shallow crustal earthquake struck 21 km NW of Ocotillo, CA, at a depth of 8.6 km and coordinates 32.8653°, -116.1560°.

Physical scale: An earthquake of magnitude 2.3 releases seismic energy equivalent to roughly 35.8 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.
