2024-12-24 19:31:24 UTC (2024-12-24) · approx. 11:31 AM UTC-8 local
On December 24, 2024 at 19:31 UTC, a magnitude 2.1 shallow crustal earthquake struck 3 km NNE of San Pedro, CA, at a depth of 11.4 km and coordinates 33.7600°, -118.2742°.
Physical scale: An earthquake of magnitude 2.1 releases seismic energy equivalent to roughly 18.6 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 16 m — a useful intuition for the size of the slip patch on the fault.
