On July 1, 2020 at 14:14 UTC, a magnitude 4.7 shallow crustal earthquake struck 47 km SSE of Inarajan Village, Guam, at a depth of 35.0 km and coordinates 12.8741°, 144.8981°.

Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
