On August 5, 2024 at 23:05 UTC, a magnitude 4.4 intermediate depth earthquake struck in the Pagan region, Northern Mariana Islands, at a depth of 234.5 km and coordinates 18.8962°, 145.4146°.

Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
