2026-05-27 19:51:36 UTC (2026-05-27) · approx. 5:51 AM UTC+10 local
On May 27, 2026 at 19:51 UTC, a magnitude 4.4 shallow crustal earthquake struck in the Maug Islands region, Northern Mariana Islands, at a depth of 10.0 km and coordinates 19.0244°, 144.8977°.
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.
