2021-09-09 21:56:46 UTC (2021-09-09) · approx. 9:56 AM UTC-12 local
On September 9, 2021 at 21:56 UTC, a magnitude 4.5 deep-focus earthquake struck 221 km ENE of Levuka, Fiji, at a depth of 559.5 km and coordinates -17.6618°, -178.6408°.
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.
