On November 26, 2020 at 21:03 UTC, a magnitude 4.3 intermediate depth earthquake struck 193 km N of Saipan, Northern Mariana Islands, at a depth of 233.8 km and coordinates 16.9616°, 145.8082°.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
