M5.0 Earthquake 215 km ENE of Levuka, Fiji — August 17, 2026
2026-08-17 00:08:07 UTC (1 hour ago) · approx. 12:08 PM UTC-12 local
Aftershock of the M5.1 mainshock.
On August 17, 2026 at 00:08 UTC, a magnitude 5.0 deep-focus earthquake struck 215 km ENE of Levuka, Fiji, at a depth of 564.4 km and coordinates -17.6896°, -178.6920°. This earthquake was detected by 89 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
This earthquake is part of an ongoing aftershock sequence following the magnitude 5.1 mainshock that occurred 4 days ago 226 km E of Levuka, Fiji. Since the mainshock, the USGS has recorded 2 aftershocks in this area. Aftershock activity is expected to continue for days to weeks as stresses on surrounding faults redistribute.
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.

Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.0 earthquakes can continue for days to weeks and gradually diminish over time.
Is this the same earthquake as the M5.1 one earlier?
No. This magnitude 5.0 earthquake is an aftershock of the larger magnitude 5.1 mainshock that occurred earlier 226 km E of Levuka, Fiji. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
