2022-01-23 18:19:47 UTC (2022-01-23) · approx. 6:19 AM UTC+12 local
On January 23, 2022 at 18:19 UTC, a magnitude 4.7 shallow crustal earthquake struck 134 km WSW of Nadi, Fiji, at a depth of 10.0 km and coordinates -18.4360°, 176.3294°.
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.
