Regional Mapping - Tasmanian Landslide Map Series Regional Mapping - Tasmanian Landslide Map Series

Regional landslide susceptibility maps, at a scale of 1:25,000 (Tasmanian Landslide Map Series), are currently being produced for the major urban areas of Tasmania using a methodology that differs significantly from earlier maps. The new maps are intended to give general guidance to Local Government (councils) on landslide susceptibility in the area covered. The maps are not intended to be used for making development decisions on a block-by-block basis in the absence of a suitable geotechnical report. The new maps supersede many of the earlier Land Stability Series and Advisory Landslide Zoning maps of the North West Coast and Tamar Valley areas. It should be noted that information from the earlier maps may have been incorporated into local government planning schemes.

Maps of the North West Coast (Boat Harbour Beach to Devonport), Tamar Valley (Launceston to George Town), Hobart and Glenorchy areas have been completed. These maps contain information on the distribution and type of known landslides and predictive susceptibility zones for rockfall, debris/earth flows, shallow slides and deep-seated landslides. Preparation of the maps has been supported by Federal Government funding programs such as the Natural Disaster Mitigation Programme and the Natural Disaster Resilience Program.

Copies of these maps and data can be obtained from MRT in paper or in digital GIS format (georeferenced raster images and shapefiles) or downloaded from our internet site in pdf format. The user guide and technical methodology can also be downloaded.

Maps of the Tasmanian Landslide Map Series can be viewed as background layers in the MRT map viewer. For index maps of the available geological maps for Tasmania refer to this page.
