On May 15, 2024 at 09:49 UTC, a magnitude 4.7 shallow crustal earthquake struck 155 km ESE of Saipan, Northern Mariana Islands, at a depth of 10.0 km and coordinates 14.4974°, 147.0027°. This earthquake was detected by 33 seismic stations with good location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
