M4.8 Earthquake south of the Fiji Islands — April 24, 2025
2025-04-24 20:04:27 UTC (2025-04-24) · approx. 8:04 AM UTC-12 local
On April 24, 2025 at 20:04 UTC, a magnitude 4.8 deep-focus earthquake struck south of the Fiji Islands, at a depth of 502.0 km and coordinates -24.2511°, -179.7960°. This earthquake was detected by 72 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 354, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 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.
