On February 12, 2026 at 23:02 UTC, a magnitude 2.6 shallow crustal earthquake struck 52 km W of Petrolia, CA, at a depth of 15.1 km and coordinates 40.3450°, -124.8938°.

Physical scale: An earthquake of magnitude 2.6 releases seismic energy equivalent to roughly 104 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 35 m — a useful intuition for the size of the slip patch on the fault.
