On December 25, 2023 at 18:38 UTC, a magnitude 4.2 shallow crustal earthquake struck 45 km SW of Puerto El Triunfo, El Salvador, at a depth of 67.3 km and coordinates 12.9652°, -88.8180°.
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.
