On September 12, 2024 at 23:09 UTC, a magnitude 3.0 shallow crustal earthquake struck 11 km N of Ocotillo Wells, CA, at a depth of 11.3 km and coordinates 33.2445°, -116.1255°.

Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 415 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 66 m — a useful intuition for the size of the slip patch on the fault.
