2023-11-26 19:34:18 UTC (2023-11-26) · approx. 5:34 AM UTC+10 local
On November 26, 2023 at 19:34 UTC, a magnitude 4.8 shallow crustal earthquake struck in the Maug Islands region, Northern Mariana Islands, at a depth of 10.0 km and coordinates 20.0915°, 145.4522°. This earthquake was detected by 61 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 354, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 km — a useful intuition for the size of the slip patch on the fault.
