On November 4, 2024 at 23:45 UTC, a magnitude 2.3 shallow crustal earthquake struck 3 km SSW of Muscoy, CA, at a depth of 9.2 km and coordinates 34.1287°, -117.3528°.

Physical scale: An earthquake of magnitude 2.3 releases seismic energy equivalent to roughly 47.1 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 24 m — a useful intuition for the size of the slip patch on the fault.
