On April 14, 2026 at 03:04 UTC, a magnitude 5.4 intermediate depth earthquake struck in the Pagan region, Northern Mariana Islands, at a depth of 212.3 km and coordinates 18.9854°, 145.4573°. The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 288 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 449, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 5.4 releases seismic energy equivalent to roughly 2 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 3.2 km — a useful intuition for the size of the slip patch on the fault.
