M4.6 Earthquake in the Fiji region — May 7, 2026
2026-05-07 13:57:40 UTC (2026-05-07) · approx. 1:57 AM UTC+12 local
On May 7, 2026 at 13:57 UTC, a magnitude 4.6 shallow crustal earthquake struck in the Fiji region, at a depth of 10.0 km and coordinates -13.7750°, 174.9824°. This earthquake was detected by 35 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — 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.
