On January 31, 2025 at 18:22 UTC, a magnitude 4.4 shallow crustal earthquake struck 37 km SW of Masachapa, Nicaragua, at a depth of 52.5 km and coordinates 11.5721°, -86.7803°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
