On July 22, 2021 at 01:28 UTC, a magnitude 5.2 shallow crustal earthquake struck 54 km SW of Masachapa, Nicaragua, at a depth of 35.0 km and coordinates 11.4920°, -86.9120°.
Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 km — a useful intuition for the size of the slip patch on the fault.
