2024-12-22 22:51:59 UTC (2024-12-22) · approx. 2:51 PM UTC-8 local
On December 22, 2024 at 22:51 UTC, a magnitude 3.0 shallow crustal earthquake struck 32 km W of Petrolia, CA, at a depth of 16.1 km and coordinates 40.2572°, -124.6558°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.
