On July 24, 2026 at 23:20 UTC, a magnitude 2.5 shallow crustal earthquake struck 7 km NE of Lake Davis, CA, at a depth of -1.6 km and coordinates 39.9098°, -120.4120°.

Physical scale: An earthquake of magnitude 2.5 releases seismic energy equivalent to roughly 76.5 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 31 m — a useful intuition for the size of the slip patch on the fault.
