On July 28, 2024 at 23:58 UTC, a magnitude 2.6 shallow crustal earthquake struck 11 km SSE of Suisun City, CA, at a depth of 22.9 km and coordinates 38.1588°, -121.9595°.

Physical scale: An earthquake of magnitude 2.6 releases seismic energy equivalent to roughly 112 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 36 m — a useful intuition for the size of the slip patch on the fault.
