2024-05-31 18:16:42 UTC (2024-05-31) · approx. 4:16 AM UTC+10 local
On May 31, 2024 at 18:16 UTC, a magnitude 4.6 shallow crustal earthquake struck 280 km N of Saipan, Northern Mariana Islands, at a depth of 10.0 km and coordinates 17.7429°, 145.6290°. This earthquake was detected by 76 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
