On August 25, 2026 at 20:17 UTC, a magnitude 3.1 shallow crustal earthquake struck 12 km WSW of Salton City, CA, at a depth of 4.3 km and coordinates 33.2393°, -116.0668°.
Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 587 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 78 m — a useful intuition for the size of the slip patch on the fault.
