M4.7 Earthquake in the Federated States of Micronesia region — June 30, 2026
2026-06-30 21:49:19 UTC (4 hours ago) · approx. 7:49 AM UTC+10 local
On June 30, 2026 at 21:49 UTC, a magnitude 4.7 shallow crustal earthquake struck in the Federated States of Micronesia region, at a depth of 10.0 km and coordinates 4.8389°, 146.4002°. This earthquake was detected by 26 seismic stations with good location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
