On September 17, 2024 at 19:36 UTC, a magnitude 3.0 shallow crustal earthquake struck 67 km WNW of Petrolia, CA, at a depth of 9.7 km and coordinates 40.4023°, -125.0742°.

Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 461 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 70 m — a useful intuition for the size of the slip patch on the fault.
