On August 17, 2024 at 11:36 UTC, a magnitude 5.3 deep-focus earthquake struck in the Fiji region, at a depth of 619.6 km and coordinates -20.9512°, -179.1893°. This earthquake was detected by 103 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 432, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 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.
