On June 13, 2024 at 21:38 UTC, a magnitude 4.8 shallow crustal earthquake struck in the Pagan region, Northern Mariana Islands, at a depth of 35.0 km and coordinates 18.7091°, 146.6340°. This earthquake was detected by 95 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.
