On September 8, 2024 at 21:45 UTC, a magnitude 2.2 shallow crustal earthquake struck 22 km WSW of Rancho Palos Verdes, CA, at a depth of -0.1 km and coordinates 33.7055°, -118.6157°.

Physical scale: An earthquake of magnitude 2.2 releases seismic energy equivalent to roughly 34.5 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 21 m — a useful intuition for the size of the slip patch on the fault.
