Landslide Planning Map Update

The Landslide Planning Map depicts both the distribution and relative susceptibility of landslides in Tasmania and underpins the state’s planning and building regulations. The map also forms the basis of the communication of landslide hazard risks to the public, through the Tasmanian Government’s Risk Ready information portal and tools that are publicly available through TasALERT.

The Landslide Planning Map was first developed in 2013 to inform the development and application of landslide (or landslip) planning and building controls in Tasmania, and this mapping is currently under review. The project Terms of Reference (PDF 155.6 KB) are available here.

The review has led to:

1. Proposed amendments to the Landslide Planning Map that consider and incorporate improvements in scientific methodology and new data;
2. A review of the rankings and thresholds for the Landslide Planning Map - Hazard Bands – Acceptable, Low, Medium, Medium-Active and High; and
3. A new Recent or Active Landslides system, which provides a mechanism to more readily incorporate information about newly-identified and expanding areas of landslide into Tasmania’s planning and building controls.

Updates to the mapping are nearly completed, with consultation workshops for the updated mapping undertaken in February and May 2024. A peer review of the products has been initiated to verify that the mapping remains true to its intended purpose, which we expect to be complete by the end of 2024.
