2022-05-06 16:00:52 UTC (2022-05-06) · approx. 2:00 AM UTC+10 local
On May 6, 2022 at 16:00 UTC, a magnitude 3.9 intermediate depth earthquake struck in the Maug Islands region, Northern Mariana Islands, at a depth of 226.1 km and coordinates 19.4231°, 145.2217°.
Physical scale: An earthquake of magnitude 3.9 releases seismic energy equivalent to roughly 11 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 296 m — a useful intuition for the size of the slip patch on the fault.
