2023-01-26 23:30:44 UTC (2023-01-26) · approx. 11:30 AM UTC+12 local
On January 26, 2023 at 23:30 UTC, a magnitude 4.7 shallow crustal earthquake struck 205 km SSE of Suva, Fiji, at a depth of 10.0 km and coordinates -19.9484°, 178.8704°. This earthquake was detected by 19 seismic stations with good location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 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.
