Purpose: This data has been published to support the Waikato Regional Hazards Portal. This data is part of the coastal hazards theme.Note layers may be slow to load.Statement: Tsunami hazard for a maximum credible event scenario, derived from tsunami modelling for populated parts of the Coromandel Peninsula (published between 2013 and 2017) and for the Firth of Thames (published 2019) and for Opoutere, Wharekawa Harbour, Kawhia Harbour, Marokopa, Awakino and Mokau (published 2022) derived from eCoast Limited modelled tsunami flood depth and speed grid data. This data illustrates the expected tsunami hazard for a modelled Maximum Credible Event scenario. For the eastern Coromandel, this scenario is a near-source tsunami resulting from an earthquake at the Tonga-Kermadec Trench. For the Firth of Thames, this scenario is regarded as a local-source tsunami resulting from an earthquake on the off-shore section of the Kerepehi Fault. For the West Coast models this is the worst case scenario selected from a variety of model scenarios and tsunami sources. The modelling was carried out using the Community Model Interface for Tsunamis (ComMIT) numerical modelling tool. Data is presented as polygons which show tsunami hazard, classified as low, medium or high hazard. The hazard classification is the same used for flood hazards. This tsunami hazard data was derived from combining tsunami depth and tsunami speed data. For the eastern Coromandel, the areas modelled include Whitianga, Mercury Bay, Cooks Beach, Hahei, Hot Water Beach, Kennedy Bay, Whangapoua, Matarangi, Kuaotunu, Opito Bay, Whangamata, Whiritoa, Pauanui and Tairua. For the Firth of Thames, the areas modelled include Colville, Coromandel, Manaia, Tapu, Te Puru, Thames, Miranda, and Whakatiwai. On the West Coast the areas modelled included Kawhia Harbour, Marokopa, Awakino and Mokau coast.Intended Use Scale: Data should not be used at scales greater than 1:2,500Data Use Limits:The data has not been smoothed and may appear to still have a "grid" like appearance. Data is derived from raster (grid) data and has many vertices. The data may be slow to load for some users.Data Specific Disclaimers:Any data sets or maps derived from this information (either published or unpublished) should comply with and contain the following disclaimer: “This map has been prepared using data supplied by the eCoast under contract to Waikato Regional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.
