On September 4, 2025 at 20:03 UTC, a magnitude 4.9 shallow crustal earthquake struck 88 km SSW of Corinto, Nicaragua, at a depth of 39.7 km and coordinates 11.7318°, -87.4590°. This earthquake was detected by 71 seismic stations with good location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
