2024-12-05 23:33:25 UTC (2024-12-05) · approx. 3:33 PM UTC-8 local
On December 5, 2024 at 23:33 UTC, a magnitude 3.0 shallow crustal earthquake struck 62 km WNW of Petrolia, CA, at a depth of 10.0 km and coordinates 40.3888°, -125.0082°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 529 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 74 m — a useful intuition for the size of the slip patch on the fault.
