On September 26, 2020 at 04:35 UTC, a magnitude 4.8 intermediate depth earthquake struck in the Pagan region, Northern Mariana Islands, at a depth of 148.9 km and coordinates 18.6205°, 145.7129°.
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.
