Hawkes Bay Earthquake Liquefaction - Hawkes Bay Regional Council

*This has superseded by the Hawke's Bay Liquefaction Web Services. Please refer to https://hbmaps.hbrc.govt.nz/arcgis/rest/services/Hazards/HawkesBay_Liquefaction/MapServer.This dataset is a subset of a larger dataset concerned with hazards in Hawke's Bay associated with earthquakes. This shape file contains information on areas in Hawke's Bay within each of which there is estimated to be a uniform non-zero potential for ground liquefaction following a large earthquake beneath or near the region. The areas are assigned rankings of ground liquefaction susceptibility associated with three hypothetical earthquakes : a magnitude 7.5 earthquake on the Mohaka fault, a magnitude 7.5 earthquake on the Poukawa fault, and a magnitude 8.1 on the tectonic plate interface beneath Hawke's Bay. The areas are also assigned an overall ranking of ground liquefaction susceptibility associated with a hypotheical large local earthquake. Further information on the derivation of the data can be found in 'Earthquake Hazard Analysis Program: Stage II:Part II - Evaluation of Liquefaction Potential in the Hawke's Bay Region' by Dellow G.D., Hengesh J.V., Heron, D., Brown L., Hull A.G., Institute of Geological and Nuclear Sciences Client Report 1999/6, 1999, for the Hawke's Bay Regional Council.
