On July 11, 2020 at 19:31 UTC, a magnitude 4.8 shallow crustal earthquake struck 31 km ESE of Inarajan Village, Guam, at a depth of 45.0 km and coordinates 13.1674°, 145.0148°.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 km — a useful intuition for the size of the slip patch on the fault.
