On March 6, 2023 at 20:32 UTC, a magnitude 4.5 shallow crustal earthquake struck 86 km SW of Jiquilillo, Nicaragua, at a depth of 41.3 km and coordinates 12.1480°, -87.9637°. This earthquake was detected by 61 seismic stations with good location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
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.
