On May 28, 2021 at 23:34 UTC, a magnitude 4.7 deep-focus earthquake struck 224 km ENE of Levuka, Fiji, at a depth of 547.0 km and coordinates -17.6098°, -178.6153°.

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.
