On November 15, 2022 at 23:49 UTC, a magnitude 2.2 shallow crustal earthquake struck 16km WNW of Lake Pillsbury, CA, at a depth of 3.3 km and coordinates 39.4867°, -123.1147°.

Physical scale: An earthquake of magnitude 2.2 releases seismic energy equivalent to roughly 34.5 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 21 m — a useful intuition for the size of the slip patch on the fault.
