On May 10, 2026 at 00:34 UTC, a magnitude 3.4 shallow crustal earthquake struck 3 km W of Brawley, CA, at a depth of 15.4 km and coordinates 32.9732°, -115.5642°.

Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 2.2 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 142 m — a useful intuition for the size of the slip patch on the fault.
