2025-04-30 22:01:59 UTC (2025-04-30) · approx. 4:01 PM UTC-6 local
On April 30, 2025 at 22:01 UTC, a magnitude 4.0 shallow crustal earthquake struck 160 km SSW of Puerto El Triunfo, El Salvador, at a depth of 10.0 km and coordinates 11.9517°, -89.1460°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
