On February 9, 2025 at 23:56 UTC, a magnitude 4.1 shallow crustal earthquake struck 16 km NNE of Potosí, Nicaragua, at a depth of 11.5 km and coordinates 11.6428°, -85.8248°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
