On October 2, 2020 at 23:31 UTC, a magnitude 5.2 intermediate depth earthquake struck in the Pagan region, Northern Mariana Islands, at a depth of 110.0 km and coordinates 18.7253°, 145.9160°.
Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 km — a useful intuition for the size of the slip patch on the fault.
