On November 4, 2022 at 16:50 UTC, a magnitude 4.5 intermediate depth earthquake struck 14 km NW of Agat Village, Guam, at a depth of 136.9 km and coordinates 13.4650°, 144.5536°. This earthquake was detected by 19 seismic stations with good 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.
