Felt by 1 person across nearby locations.
On May 10, 2026 at 21:08 UTC, a magnitude 4.5 intermediate depth earthquake struck 297 km N of Saipan, Northern Mariana Islands, at a depth of 230.2 km and coordinates 17.9018°, 145.7075°. This earthquake was detected by 59 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
