The tsunami evacuation zones for Thorndon/Pipitea we used in 2014/15 were based a regional modelling project undertaken in 2008. The inundation estimates were based on an empirical ‘rule-based’ tsunami height attenuation modelling technique.

However the latest definition for the tsunami evacuation zones are a little different. These have been calculated using more detailed hydrodynamic inundation modelling of Wellington Harbour undertaken in 2015.
