On June 30, 2020 at 19:31 UTC, a magnitude 4.0 shallow crustal earthquake struck 124 km SSW of La Esperanza (El Zapotal), Mexico, at a depth of 14.9 km and coordinates 14.4551°, -93.7110°.

Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
