On June 23, 2026 at 01:56 UTC, a magnitude 5.1 shallow crustal earthquake struck 187 km N of Fais, Micronesia, at a depth of 35.0 km and coordinates 11.4577°, 140.5295°. This earthquake was detected by 209 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 400, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 km — a useful intuition for the size of the slip patch on the fault.
