On January 3, 2024 at 21:29 UTC, a magnitude 4.1 shallow crustal earthquake struck in the Maug Islands region, Northern Mariana Islands, at a depth of 10.0 km and coordinates 19.9803°, 145.0811°.

Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
