On June 21, 2024 at 19:14 UTC, a magnitude 5.0 shallow crustal earthquake struck 278 km WSW of Sigatoka, Fiji, at a depth of 14.6 km and coordinates -19.3856°, 175.2107°. This earthquake was detected by 99 seismic stations with good location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 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.
