2026-06-05 22:08:11 UTC (2026-06-05) · approx. 10:08 AM UTC+12 local
On June 5, 2026 at 22:08 UTC, a magnitude 4.5 deep-focus earthquake struck 31 km N of Nasinu, Fiji, at a depth of 563.1 km and coordinates -17.7843°, 178.5344°. This earthquake was detected by 61 seismic stations with good 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.
The epicenter is located in Fiji, a region characterized by the Fiji Fracture Zone at the junction of the Pacific and Australian plates, with deep-focus seismicity from the subducted slab. View all earthquakes in Fiji.
