New Zealand - Waimakariri Liquefaction Susceptibility - Canterbury Maps

The dataset shows zones of different liquefaction susceptibility within Waimakariri district.The dataset is based on the 1:250,000 liquefaction potential maps (Figure7.1) in Yetton & McCahon (2009) Earthquake Hazard Assessment for Waimakariri District. Environment Canterbury report number R09/32, but uses the more accurate boundaries of geological units directly from the GNS Science QMAP (1:250,000) geological map series as the zone boundaries. The Yetton & McCahon (2009) report also used the surface geology from the GNS Science QMAP series, with limited borehole information, to delineate areas of liquefaction potential, but the maps in the report were not developed in GIS and are not adequately georeferenced. NOTE: The eastern part of this dataset has been superseded by Brackley, H. (comp), 2012, Review of liquefaction hazard information in Eastern Canterbury, including Christchurch City and parts of Selwyn, Waimakariri and Hurunui Districts. Environment Canterbury report number R12/83.
