2025-12-11 22:08:08 UTC (2025-12-11) · approx. 10:08 AM UTC-12 local
On December 11, 2025 at 22:08 UTC, a magnitude 5.1 deep-focus earthquake struck 258 km E of Levuka, Fiji, at a depth of 575.9 km and coordinates -18.1107°, -178.2408°. This earthquake was detected by 89 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 400, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 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.
