On July 12, 2026 at 20:52 UTC, a magnitude 2.9 shallow crustal earthquake struck 13 km S of New Idria, CA, at a depth of 15.3 km and coordinates 36.2968°, -120.6523°.

Physical scale: An earthquake of magnitude 2.9 releases seismic energy equivalent to roughly 374 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 63 m — a useful intuition for the size of the slip patch on the fault.
