On August 14, 2022 at 21:27 UTC, a magnitude 2.3 shallow crustal earthquake struck 14km SE of Bayside, CA, at a depth of 21.8 km and coordinates 40.7513°, -123.9567°.

Physical scale: An earthquake of magnitude 2.3 releases seismic energy equivalent to roughly 45.5 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 24 m — a useful intuition for the size of the slip patch on the fault.
