On January 23, 2025 at 20:03 UTC, a magnitude 4.5 shallow crustal earthquake struck 104 km ESE of Yigo Village, Guam, at a depth of 10.0 km and coordinates 13.0732°, 145.7334°. This earthquake was detected by 62 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
