M5.1 Earthquake south of the Fiji Islands — April 5, 2022
2022-04-05 20:24:27 UTC (2022-04-05) · approx. 8:24 AM UTC-12 local
On April 5, 2022 at 20:24 UTC, a magnitude 5.1 shallow crustal earthquake struck south of the Fiji Islands, at a depth of 37.9 km and coordinates -25.5675°, -176.5609°.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 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.
