On February 1, 2022 at 18:05 UTC, a magnitude 2.5 shallow crustal earthquake struck 11km SE of Pinnacles, CA, at a depth of 3.3 km and coordinates 36.4708°, -121.0445°.

Physical scale: An earthquake of magnitude 2.5 releases seismic energy equivalent to roughly 84.8 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 32 m — a useful intuition for the size of the slip patch on the fault.
