2024-03-24 13:12:22 UTC (2024-03-24) · approx. 1:12 AM UTC+12 local
On March 24, 2024 at 13:12 UTC, a magnitude 4.9 shallow crustal earthquake struck 122 km W of Nadi, Fiji, at a depth of 10.0 km and coordinates -17.7180°, 176.2629°. This earthquake was detected by 27 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 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.
