On September 23, 2026 at 10:52 UTC, a magnitude 2.6 shallow crustal earthquake struck 9 km WNW of Anza, CA, at a depth of 12.6 km and coordinates 33.5740°, -116.7702°.

Physical scale: An earthquake of magnitude 2.6 releases seismic energy equivalent to roughly 133 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 39 m — a useful intuition for the size of the slip patch on the fault.
