On July 8, 2023 at 20:12 UTC, a magnitude 4.4 shallow crustal earthquake struck 43 km SSW of Puerto El Triunfo, El Salvador, at a depth of 57.6 km and coordinates 12.9018°, -88.6628°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
