On August 10, 2022 at 21:48 UTC, a magnitude 4.3 intermediate depth earthquake struck 35 km NNW of Yigo Village, Guam, at a depth of 119.9 km and coordinates 13.8317°, 144.7693°.

Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
