On July 14, 2025 at 23:24 UTC, a magnitude 4.3 intermediate depth earthquake struck in the Pagan region, Northern Mariana Islands, at a depth of 192.7 km and coordinates 18.5166°, 145.6365°.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
