On March 1, 2021 at 22:13 UTC, a magnitude 2.7 shallow crustal earthquake struck 20km N of Searles Valley, CA, at a depth of 3.1 km and coordinates 35.9478°, -117.3602°.

Physical scale: An earthquake of magnitude 2.7 releases seismic energy equivalent to roughly 163 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 43 m — a useful intuition for the size of the slip patch on the fault.
