M4.7 Earthquake south of the Fiji Islands — January 5, 2024
2024-01-05 16:59:03 UTC (2024-01-05) · approx. 4:59 AM UTC+12 local
On January 5, 2024 at 16:59 UTC, a magnitude 4.7 deep-focus earthquake struck south of the Fiji Islands, at a depth of 500.6 km and coordinates -24.7291°, 179.7373°. This earthquake was detected by 49 seismic stations with good location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.
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.
