2020-12-06 22:38:37 UTC (2020-12-06) · approx. 10:38 AM UTC-12 local
On December 6, 2020 at 22:38 UTC, a magnitude 4.7 deep-focus earthquake struck 291 km SE of Levuka, Fiji, at a depth of 632.2 km and coordinates -20.1227°, -178.9500°.
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.
