On November 7, 2025 at 17:31 UTC, a magnitude 4.5 deep-focus earthquake struck 251 km E of Levuka, Fiji, at a depth of 530.0 km and coordinates -17.9963°, -178.3069°. This earthquake was detected by 133 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.

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.
