Modelled Tsunami Hazard Class
收藏资源简介：
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. WRC Natural Hazard Information Hierarchy: 2. Local to regional scale Information that is suitable to be used for District or Regional Plans, or as an initial indicator of where further investigation may be required. This information is NOT suitable for use at property scale, or for: • property specific risk assessments • resource or building consents • decisions that concern personal or public safety • the conduct of commercial business • insurance purposes Waikato Regional Council recommends further investigation and using other applicable natural hazard data, if available, for property specific purposes. The information is generally based on modelling or hazard mapping but may not include both current and future possible scenarios. Users should make sure they are using the most appropriate natural hazards data available. Data held by other organisations may be better suited for property scale use or may be more up to date. Before using any of the Waikato Regional Council natural hazard data at property scale or for subdivision development purposes please contact the Waikato Regional Council Regional Resilience team for guidance. Note that further information on resource consenting is available here. Intended Use Scale: Data should not be used at scales greater than 1:2,500 Data 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. Unless otherwise agreed in writing, all liability of eCoast to any party other than Waikato Regional Council in respect of the map is expressly excluded”. “The presence of a hazard zone on this map does not guarantee the existence of such a hazard, nor does the lack of information preclude the existence of a hazard or risk. Waikato Regional Council, while providing the information in good faith, accepts no responsibility for any loss, damage, injury, or loss in value of any person, property, service or otherwise resulting from hazards or knowledge of hazards in the Waikato Region.” The standard Waikato Regional Council Disclaimer applies to this data “While Waikato Regional Council has exercised all reasonable skill and care in controlling the contents of this information, Waikato Regional Council accepts no liability in contract, tort or otherwise howsoever, for any loss, damage, injury or expense (whether direct, indirect or consequential) arising out of the provision of this information or its use by you.” WRC Metadata: See full metadata by searching for 'HAZARD.sdeadmin.HAZ_MOD_TSUNAMI_HAZARD_CLASS' under HAZARDS - Regional Hazards Portal - GIS Layers Terms of Use: This work is licensed under a Creative Commons Attribution-NoDerivatives 4.0 International License.
