On June 23, 2020 at 21:27 UTC, a magnitude 4.2 shallow crustal earthquake struck 8 km SSW of Puerto Ángel, Mexico, at a depth of 10.0 km and coordinates 15.5938°, -96.5216°.0

Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
