On August 1, 2026 at 11:35 UTC, a magnitude 2.8 shallow crustal earthquake struck 7 km ESE of Cloverdale, CA, at a depth of 6.3 km and coordinates 38.7717°, -122.9478°.

Physical scale: An earthquake of magnitude 2.8 releases seismic energy equivalent to roughly 208 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 48 m — a useful intuition for the size of the slip patch on the fault.
