On November 4, 2020 at 19:54 UTC, a magnitude 4.5 shallow crustal earthquake struck 91 km SW of San Juan del Sur, Nicaragua, at a depth of 10.0 km and coordinates 10.7466°, -86.5375°.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
