On November 29, 2025 at 18:10 UTC, a magnitude 2.9 shallow crustal earthquake struck 9 km ENE of Rancho Tehama Reserve, CA, at a depth of 62.1 km and coordinates 40.0542°, -122.3072°.

Physical scale: An earthquake of magnitude 2.9 releases seismic energy equivalent to roughly 388 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 64 m — a useful intuition for the size of the slip patch on the fault.
