Felt by 11 people across nearby locations.
On June 7, 2020 at 03:42 UTC, a magnitude 4.9 shallow crustal earthquake struck 97 km NNW of Ba, Fiji, at a depth of 10.0 km and coordinates -16.6884°, 177.4053°.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 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.
