On October 22, 2020 at 21:02 UTC, a magnitude 2.7 shallow crustal earthquake struck 8km WSW of Niland, CA, at a depth of 2.2 km and coordinates 33.2065°, -115.5900°.

Physical scale: An earthquake of magnitude 2.7 releases seismic energy equivalent to roughly 188 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 46 m — a useful intuition for the size of the slip patch on the fault.
