On May 24, 2024 at 23:31 UTC, a magnitude 4.5 intermediate depth earthquake struck in the Maug Islands region, Northern Mariana Islands, at a depth of 152.6 km and coordinates 19.2696°, 145.6571°. This earthquake was detected by 78 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
