2023-06-24 04:31:10 UTC (2023-06-24) · approx. 2:31 PM UTC+10 local
On June 24, 2023 at 04:31 UTC, a magnitude 4.6 shallow crustal earthquake struck 180 km ESE of Saipan, Northern Mariana Islands, at a depth of 10.0 km and coordinates 14.8953°, 147.4039°. This earthquake was detected by 22 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.
