On October 1, 2025 at 18:18 UTC, a magnitude 4.3 intermediate depth earthquake struck 14 km SSE of Nagarote, Nicaragua, at a depth of 162.1 km and coordinates 12.1522°, -86.4944°.

Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
