On September 4, 2025 at 04:37 UTC, a magnitude 5.2 shallow crustal earthquake struck 254 km NE of Fais, Micronesia, at a depth of 10.0 km and coordinates 11.6636°, 141.8368°. This earthquake was detected by 93 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 416, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 km — a useful intuition for the size of the slip patch on the fault.
