On September 5, 2025 at 21:48 UTC, a magnitude 4.5 intermediate depth earthquake struck 13 km NNE of Potosí, Nicaragua, at a depth of 195.0 km and coordinates 11.6148°, -85.8245°. This earthquake was detected by 40 seismic stations with good location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
