Purpose: This data has been published to support the Waikato Regional Hazards Portal. This data is part of the Coastal hazards theme.Statement: Model boundaries for the maximum credible event tsunami modelling carried out for the Coromandel (published between 2013 and 2017), Firth of Thames (published 2019) and Opoutere, Kawhia Harbour, Marokopa, Awakino and Mokau (published 2022), by eCoast limited. Preliminary modelling (to show tsunami susceptible areas) carried out for other populated parts of the West Coast (published 2015), by eCoast limited. The model boundaries show which areas were included in the modelling. Areas that are outside of the tsunami model boundaries have not been modelled but may still be at risk of tsunami inundation. For the Coromandel, Firth of Thames, Kawhia Harbour, Marokopa, Awakino and Mokau the modelling was carried out using the Community Model Interface for Tsunamis (ComMIT) numerical modelling tool. For the remaining parts of the West Coast, only preliminary modelling and investigation has been undertaken (as the preliminary results showed that wave heights are likely to be relatively small, and there will likely be time for an official tsunami warning). For more information on tsunami evacuation, including Community Response Plans, the Emergency Management staff for the relevant District Council should be contacted. More detailed information on the numerical modelling carried out by eCoast Limited can be found on the Waikato Regional Council tsunami webpages.WRC Spatial Information carried out GIS work in 2022 and 2023 to create the bounding boxes representing the model boundaries for five new models for Port Charles, Opoutere and Wharekawa Harbour, Kawhia Harbour, Marokopa, and Mokau/Awakino. This work also involved splitting out the new model areas from existing preliminary model areas where they overlapped for Kawhia Harbour, Marokopa, and Mokau/Awakino.Intended Use Scale: Data should not be used at scales greater than 1:1,000Data Use Limits:As per statement above and disclaimers below.Data Specific Disclaimers:Any data sets or maps derived from this information (either published or unpublished) should comply with and contain the following disclaimer: “This map has been prepared using data supplied by the eCoast under contract to Waikato Regional Council.
