2024-09-30 19:30:28 UTC (2024-09-30) · approx. 5:30 AM UTC+10 local
On September 30, 2024 at 19:30 UTC, a magnitude 4.4 intermediate depth earthquake struck in the Maug Islands region, Northern Mariana Islands, at a depth of 111.6 km and coordinates 20.8568°, 144.9069°.
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.
