On November 9, 2022 at 09:51 UTC, a magnitude 7.0 deep-focus earthquake struck south of the Fiji Islands, at a depth of 660.0 km and coordinates -26.0901°, 178.3427°. The earthquake was reported felt by 3 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 2.6 (weak). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 142 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 755, making it a moderate-impact event.

Physical scale: An earthquake of magnitude 7.0 releases seismic energy equivalent to roughly 477 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 41 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.
