On February 28, 2024 at 17:38 UTC, a magnitude 3.8 shallow crustal earthquake struck 39 km SE of Golfo de Santa Clara, Mexico, at a depth of 13.3 km and coordinates 31.4139°, -114.2290°.

Physical scale: An earthquake of magnitude 3.8 releases seismic energy equivalent to roughly 7.6 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 252 m — a useful intuition for the size of the slip patch on the fault.
