2024-09-19 21:40:05 UTC (2024-09-19) · approx. 7:40 AM UTC+10 local
On September 19, 2024 at 21:40 UTC, a magnitude 4.2 shallow crustal earthquake struck 167 km ESE of Saipan, Northern Mariana Islands, at a depth of 10.0 km and coordinates 14.8641°, 147.2749°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
