On July 18, 2025 at 06:49 UTC, a magnitude 5.1 shallow crustal earthquake struck 102 km S of Puerto San José, Guatemala, at a depth of 10.0 km and coordinates 13.0165°, -90.9706°. This earthquake was detected by 71 seismic stations with good location accuracy and was assigned a USGS significance rating of 400, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 km — a useful intuition for the size of the slip patch on the fault.
