On June 29, 2026 at 21:27 UTC, a magnitude 4.2 shallow crustal earthquake struck 44 km SW of Puerto El Triunfo, El Salvador, at a depth of 61.2 km and coordinates 12.9535°, -88.7883°.
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.
