On August 2, 2026 at 05:13 UTC, a magnitude 4.3 shallow crustal earthquake struck 159 km ESE of Saipan, Northern Mariana Islands, at a depth of 10.0 km and coordinates 14.6668°, 147.1236°.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
