On November 13, 2022 at 22:28 UTC, a magnitude 5.0 deep-focus earthquake struck in the Mariana Islands region, at a depth of 322.5 km and coordinates 21.5090°, 143.1030°. This earthquake was detected by 112 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.
