On May 14, 2023 at 21:35 UTC, a magnitude 2.4 shallow crustal earthquake struck 45km WSW of Coronado, CA, at a depth of 5.9 km and coordinates 32.5427°, -117.6370°.

Physical scale: An earthquake of magnitude 2.4 releases seismic energy equivalent to roughly 54.1 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 26 m — a useful intuition for the size of the slip patch on the fault.
