2024-09-17 18:53:21 UTC (2024-09-17) · approx. 10:53 AM UTC-8 local
On September 17, 2024 at 18:53 UTC, a magnitude 3.2 shallow crustal earthquake struck 69 km WNW of Petrolia, CA, at a depth of 10.0 km and coordinates 40.3912°, -125.0892°.
Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 1.0 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 100 m — a useful intuition for the size of the slip patch on the fault.
