On December 25, 2022 at 05:43 UTC, a magnitude 5.1 intermediate depth earthquake struck in the Pagan region, Northern Mariana Islands, at a depth of 239.2 km and coordinates 18.5988°, 145.4632°. This earthquake was detected by 110 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 400, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 km — a useful intuition for the size of the slip patch on the fault.
