On July 25, 2024 at 11:18 UTC, a magnitude 4.7 shallow crustal earthquake struck 216 km SSW of Colonia, Micronesia, at a depth of 13.3 km and coordinates 7.8196°, 137.1321°. This earthquake was detected by 51 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
