On March 12, 2025 at 19:36 UTC, a magnitude 4.1 shallow crustal earthquake struck 41 km SW of Puerto El Triunfo, El Salvador, at a depth of 59.3 km and coordinates 13.0264°, -88.8295°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
