On June 7, 2021 at 18:03 UTC, a magnitude 4.7 intermediate depth earthquake struck in the Pagan region, Northern Mariana Islands, at a depth of 237.0 km and coordinates 18.7241°, 145.4847°.
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.
