M3.2 Earthquake 96 km WNW of Petrolia, CA — December 10, 2024
2024-12-10 21:50:44 UTC (2024-12-10) · approx. 1:50 PM UTC-8 local
On December 10, 2024 at 21:50 UTC, a magnitude 3.2 shallow crustal earthquake struck 96 km WNW of Petrolia, CA, at a depth of 4.8 km and coordinates 40.4120°, -125.4128°.
Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 1.1 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 104 m — a useful intuition for the size of the slip patch on the fault.
