On November 30, 2025 at 16:23 UTC, a magnitude 4.7 intermediate depth earthquake struck in the Pagan region, Northern Mariana Islands, at a depth of 201.5 km and coordinates 18.8501°, 145.7151°. This earthquake was detected by 96 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
