On December 8, 2024 at 23:23 UTC, a magnitude 3.9 intermediate depth earthquake struck in the Pagan region, Northern Mariana Islands, at a depth of 214.7 km and coordinates 18.9493°, 145.3205°.
Physical scale: An earthquake of magnitude 3.9 releases seismic energy equivalent to roughly 11 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 296 m — a useful intuition for the size of the slip patch on the fault.
