On June 15, 2024 at 05:35 UTC, a magnitude 4.6 shallow crustal earthquake struck 217 km SSW of Colonia, Micronesia, at a depth of 10.0 km and coordinates 7.8135°, 137.1248°. This earthquake was detected by 48 seismic stations with good 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.
