Dataset TitleEarthquake Hazard Zones
CustodianData Authority: Department of Planning, Transport and Infrastructure
Data Provider: Department of Planning, Transport and Infrastructure

Description

DescriptionEarthquake Hazard Zones are used in conjunction with the Building Code of Australia (BCA) for use with the design of domestic structures in accordance with Appendix A Domestic Structures (Housing) of AS 1170.4. Earthquake Hazard Zones are classified INTO 2 zones –- 1) Areas identified as having a hazard factor (Z) of more than 0.11SELECT 1 FROM DUAL; 2) Areas identified as having a hazard factor (Z) of 0.11 or less
UsageTo assist in the application of the Building Code. For use with the design of domestic structures in accordance with Appendix A Domestic Structures (Housing) of AS 1170.4.

Data Quality

LineageEarthquake Hazard Zones cover the whole state and derived from the Earthquake Hazard Risk Contour Map sourced from Geoscience Australia from https://data.gov.au/dataset/earthquake-hazard-risk-contour-map-national-geoscience-dataset. The source data is an interpretive data set based on data derived from AGSO's World Earthquake Database. Using earthquake locations and measurements from the database, contours reflecting potential earthquake hazard were digitised in Arcinfo for the Australian mainland. In 1997 the 1:1 000 000 scale AGSO approved coastline was added. map
