On June 6, 2020 at 18:38 UTC, a magnitude 2.1 shallow crustal earthquake struck 21km SSW of Lompoc, CA, at a depth of 0.8 km and coordinates 34.4625°, -120.5387°.

Physical scale: An earthquake of magnitude 2.1 releases seismic energy equivalent to roughly 19.2 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 16 m — a useful intuition for the size of the slip patch on the fault.
