On December 9, 2020 at 04:56 UTC, a magnitude 4.9 shallow crustal earthquake struck 103 km SW of Jiquilillo, Nicaragua, at a depth of 10.0 km and coordinates 12.0679°, -88.1070°.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
