2024-08-08 18:17:08 UTC (2024-08-08) · approx. 4:17 AM UTC+10 local
On August 8, 2024 at 18:17 UTC, a magnitude 4.1 intermediate depth earthquake struck in the Maug Islands region, Northern Mariana Islands, at a depth of 128.2 km and coordinates 19.0806°, 145.9012°.
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.
