Wellington Region Liquefaction Potential

The occurrence of earthquakes in the Wellington Region is inevitable due to its location at the boundary of two crustal plates. Earthquakes have the potential to cause significant adverse effects within the Region, including loss of life, injury, and social and economic disruption. In recognition of these potential effects, the Wellington Regional Council initiated a project in 1988 to:Assess the risks posed by earthquakes.Identify mitigation options.Implementmeasures to ensure that the level of risk is acceptable.The purpose of the maps is to show the areas susceptible to liquefaction, and the geographic variation in liquefaction potential and liquefaction ground damage.The risk posed in each location is shown both numerically through the "SED_CODE" field and categorically through the "POTENTIAL". The SED_CODE values rank the features from 1 through to 3 showing Low to High categories in the POTENTIAL field. 4 was used for Variable areas and 9 used for No potentialLiquefaction potential in the Wellington Region urban areas. This dataset is a compilation of the "liquefaction potential" ArcInfo coverage series with accompanying notes (Publication WRC/PP-T-93/73).
