On February 14, 2026 at 20:25 UTC, a magnitude 4.1 intermediate depth earthquake struck in the Pagan region, Northern Mariana Islands, at a depth of 215.6 km and coordinates 18.6289°, 145.7666°.

Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
