On April 19, 2024 at 22:44 UTC, a magnitude 4.1 deep-focus earthquake struck 144 km NNW of Saipan, Northern Mariana Islands, at a depth of 303.0 km and coordinates 16.4865°, 145.4515°.
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.
