On July 29, 2024 at 12:11 UTC, a magnitude 5.7 deep-focus earthquake struck 242 km ENE of Levuka, Fiji, at a depth of 581.0 km and coordinates -17.5624°, -178.4551°. The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 132 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 500, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 5.7 releases seismic energy equivalent to roughly 5 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 5.2 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.
