On April 6, 2021 at 21:33 UTC, a magnitude 4.2 intermediate depth earthquake struck 38 km SSW of Corinto, Nicaragua, at a depth of 70.3 km and coordinates 12.1587°, -87.2913°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
