2024-03-29 04:58:59 UTC (2024-03-29) · approx. 2:58 PM UTC+10 local
On March 29, 2024 at 04:58 UTC, a magnitude 5.0 shallow crustal earthquake struck 258 km NE of Saipan, Northern Mariana Islands, at a depth of 41.6 km and coordinates 17.0572°, 147.2408°. This earthquake was detected by 72 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
