2024-02-28 21:36:08 UTC (2024-02-28) · approx. 9:36 AM UTC-12 local
On February 28, 2024 at 21:36 UTC, a magnitude 4.9 deep-focus earthquake struck 243 km ENE of Levuka, Fiji, at a depth of 550.3 km and coordinates -17.5386°, -178.4580°. This earthquake was detected by 111 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.
