On October 26, 2020 at 07:24 UTC, a magnitude 4.6 intermediate depth earthquake struck in the Pagan region, Northern Mariana Islands, at a depth of 191.7 km and coordinates 18.5653°, 145.7463°.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
