On January 27, 2025 at 14:51 UTC, a magnitude 5.3 intermediate depth earthquake struck in the Pagan region, Northern Mariana Islands, at a depth of 143.9 km and coordinates 18.0413°, 146.0169°. This earthquake was detected by 139 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 432, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 km — a useful intuition for the size of the slip patch on the fault.
