On September 15, 2026 at 20:00 UTC, a magnitude 2.4 shallow crustal earthquake struck 3 km WNW of Dublin, CA, at a depth of 10.0 km and coordinates 37.7090°, -121.9647°.

Physical scale: An earthquake of magnitude 2.4 releases seismic energy equivalent to roughly 60.0 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 27 m — a useful intuition for the size of the slip patch on the fault.
