On October 17, 2022 at 23:01 UTC, a magnitude 4.6 intermediate depth earthquake struck near Nicaragua, at a depth of 181.1 km and coordinates 11.3285°, -85.6861°. This earthquake was detected by 78 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
