On July 27, 2025 at 03:06 UTC, a magnitude 4.8 shallow crustal earthquake struck 95 km SSW of Puerto El Triunfo, El Salvador, at a depth of 35.0 km and coordinates 12.4439°, -88.7541°. This earthquake was detected by 50 seismic stations with good location accuracy and was assigned a USGS significance rating of 354, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 km — a useful intuition for the size of the slip patch on the fault.
