Expected intensity

south of the Fiji IslandsNatural Earth
  • MMI II ≤ 100 km

Rings show the expected Modified Mercalli (MMI) intensity from the Akkar–Sandıkkaya–Bommer (2014) ground-motion model converted with Worden et al. (2012). Real shaking depends on soil and building.

Aftershocks

Earthquakes within 20 km of the epicentre in the first 30 days.

No aftershocks recorded yet.

Aftershock forecast

The chance of an aftershock of magnitude 4 or more in the next 7 days is 10%, and of magnitude 5 or more 1%.
The chance of an aftershock of magnitude 3 or more in the next 24 hours is 26%.

≈ expected number of aftershocks

0 aftershocks recorded so far within 10 km (0 of M3.9 or more).

Computed: . Method: Reasenberg-Jones (generic, Bayesian a-value update); regime ANSR-DEEPCON; generic parameters Page et al. (2016) via USGS OpenSHA GenericRJ_ParametersFetch.json. Probabilities are updated with the recorded aftershocks on every request. (b = 1, p = 0.98, c = 0.018 days, a = -2.345)

This is a statistical forecast, not an earthquake prediction. Actual aftershock activity can differ; follow local authorities for official statements.
