On May 22, 2024 at 21:47 UTC, a magnitude 4.2 intermediate depth earthquake struck in the Pagan region, Northern Mariana Islands, at a depth of 144.1 km and coordinates 18.4979°, 145.4391°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
