On April 25, 2024 at 09:09 UTC, a magnitude 5.1 shallow crustal earthquake struck 141 km ESE of Saipan, Northern Mariana Islands, at a depth of 10.0 km and coordinates 14.5517°, 146.8815°.0 This earthquake was detected by 90 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 400, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 km — a useful intuition for the size of the slip patch on the fault.
