On December 29, 2024 at 23:00 UTC, a magnitude 4.0 intermediate depth earthquake struck 9 km NW of San Juan del Sur, Nicaragua, at a depth of 100.9 km and coordinates 11.3207°, -85.9299°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
