On May 27, 2025 at 02:57 UTC, a magnitude 5.0 shallow crustal earthquake struck 71 km SE of Inarajan Village, Guam, at a depth of 10.0 km and coordinates 12.8969°, 145.2843°. This earthquake was detected by 110 seismic stations with good location accuracy and was assigned a USGS significance rating of 390, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
