On August 27, 2026 at 19:06 UTC, a magnitude 4.4 intermediate depth earthquake struck in the Pagan region, Northern Mariana Islands, at a depth of 218.9 km and coordinates 18.6991°, 145.6078°.

Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
