On June 5, 2023 at 22:40 UTC, a magnitude 2.7 shallow crustal earthquake struck 32km S of Santa Barbara Is., CA, at a depth of -0.1 km and coordinates 33.1833°, -119.0903°.

Physical scale: An earthquake of magnitude 2.7 releases seismic energy equivalent to roughly 153 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 42 m — a useful intuition for the size of the slip patch on the fault.
