On May 10, 2024 at 19:29 UTC, a magnitude 4.5 shallow crustal earthquake struck 162 km ENE of Saipan, Northern Mariana Islands, at a depth of 32.2 km and coordinates 15.8282°, 147.1308°. This earthquake was detected by 56 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.
