Wellington Region Tsunami Evacuation Zones. Wellington region tsunami evacuation data containing three zones; red, orange and yellow, corresponding to different threat levels.
The layer was manually digitised onto orthophoto coverage based on raw polygon data derived from tsunami modelling and verified with elevation data to ensure accuracy and consistency.
The zones are based on probabilistic tsunami wave heights derived from previously recorded events that have affected the Wellington region and modelling tsunami from known source areas.
The risk varies around the Wellington region. It is highest along the Wairarapa and south coast, moderate around Wellington Harbour and low to moderate around Porirua and along the Kapiti Coast.
