2023-07-24 02:49:56 UTC (2023-07-24) · approx. 2:49 PM UTC+12 local
On July 24, 2023 at 02:49 UTC, a magnitude 6.0 deep-focus earthquake struck 665 km S of Suva, Fiji, at a depth of 523.0 km and coordinates -24.0956°, 178.7423°. The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 117 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 554, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 6.0 releases seismic energy equivalent to roughly 15 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 8.3 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.
