On December 25, 2023 at 18:50 UTC, a magnitude 2.3 shallow crustal earthquake struck 10 km ENE of Cambria, CA, at a depth of 3.2 km and coordinates 35.5862°, -120.9763°.

Physical scale: An earthquake of magnitude 2.3 releases seismic energy equivalent to roughly 39.7 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 23 m — a useful intuition for the size of the slip patch on the fault.
