2025-09-15 20:29:21 UTC (2025-09-15) · approx. 8:29 AM UTC-12 local
On September 15, 2025 at 20:29 UTC, a magnitude 4.7 deep-focus earthquake struck 299 km E of Levuka, Fiji, at a depth of 629.0 km and coordinates -17.9551°, -177.8607°. This earthquake was detected by 58 seismic stations with excellent 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.
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.
