M5.2 Earthquake in the Fiji region — April 28, 2026
2026-04-28 15:28:16 UTC (1 hour ago) · approx. 3:28 AM UTC-12 local
On April 28, 2026 at 15:28 UTC, a magnitude 5.2 deep-focus earthquake struck in the Fiji region, at a depth of 409.0 km and coordinates -18.4920°, -177.5758°. This earthquake was detected by 86 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 416, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 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.
