On November 19, 2023 at 23:22 UTC, a magnitude 4.1 shallow crustal earthquake struck 24 km SSW of Masachapa, Nicaragua, at a depth of 60.4 km and coordinates 11.5740°, -86.5711°.

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.
