On September 20, 2026 at 03:43 UTC, a magnitude 5.3 shallow crustal earthquake struck 108 km ESE of Yigo Village, Guam, at a depth of 10.0 km and coordinates 13.0568°, 145.7591°. This earthquake was detected by 50 seismic stations with good location accuracy and was assigned a USGS significance rating of 432, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 km — a useful intuition for the size of the slip patch on the fault.
