2021-08-08 21:38:31 UTC (2021-08-08) · approx. 9:38 AM UTC-12 local
On August 8, 2021 at 21:38 UTC, a magnitude 4.5 deep-focus earthquake struck 296 km E of Levuka, Fiji, at a depth of 597.3 km and coordinates -17.5670°, -177.9391°.
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.
