2024-11-30 10:33:40 UTC (2024-11-30) · approx. 8:33 PM UTC+10 local
On November 30, 2024 at 10:33 UTC, a magnitude 5.1 intermediate depth earthquake struck 253 km N of Saipan, Northern Mariana Islands, at a depth of 198.5 km and coordinates 17.5037°, 145.8664°. This earthquake was detected by 111 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.
