2026-07-23 09:03:52 UTC (1 hour ago) · approx. 1:03 AM UTC-8 local
On July 23, 2026 at 09:03 UTC, a magnitude 2.8 shallow crustal earthquake struck 6 km S of Brawley, CA, at a depth of 11.6 km and coordinates 32.9203°, -115.5307°.
Physical scale: An earthquake of magnitude 2.8 releases seismic energy equivalent to roughly 215 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 49 m — a useful intuition for the size of the slip patch on the fault.
