On August 21, 2024 at 18:08 UTC, a magnitude 4.4 shallow crustal earthquake struck 184 km ESE of Saipan, Northern Mariana Islands, at a depth of 10.0 km and coordinates 14.5925°, 147.3464°.
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.
