On October 20, 2026 at 02:54 UTC, a magnitude 5.0 intermediate depth earthquake struck in the Pagan region, Northern Mariana Islands, at a depth of 129.4 km and coordinates 18.2529°, 146.0345°. This earthquake was detected by 71 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
