On October 29, 2020 at 19:01 UTC, a magnitude 4.6 shallow crustal earthquake struck 53 km SW of San Francisco Menéndez, El Salvador, at a depth of 56.2 km and coordinates 13.4891°, -90.3485°.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
