On August 18, 2022 at 20:45 UTC, a magnitude 4.4 intermediate depth earthquake struck 14 km ESE of Jiquilillo, Nicaragua, at a depth of 143.5 km and coordinates 12.6950°, -87.3280°.
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.
