On January 12, 2021 at 20:02 UTC, a magnitude 2.2 shallow crustal earthquake struck 6km NE of Chatsworth, CA, at a depth of 5.6 km and coordinates 34.2947°, -118.5618°.

Physical scale: An earthquake of magnitude 2.2 releases seismic energy equivalent to roughly 29.1 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 20 m — a useful intuition for the size of the slip patch on the fault.
