On November 11, 2025 at 15:34 UTC, a magnitude 4.6 shallow crustal earthquake struck 240 km N of Fais, Micronesia, at a depth of 44.8 km and coordinates 11.9370°, 140.5547°. This earthquake was detected by 127 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
