M5.3 Earthquake in the Fiji region — October 30, 2020
2020-10-30 02:34:21 UTC (2020-10-30) · approx. 2:34 PM UTC-12 local
On October 30, 2020 at 02:34 UTC, a magnitude 5.3 deep-focus earthquake struck in the Fiji region, at a depth of 574.7 km and coordinates -20.8413°, -178.5491°.
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 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.
