A Method Of Zoning Landslide Hazard

Patrick MacGregor and Brett Taylor

This paper describes a method for the zoning of landslide hazard using a standard site report and frequency analysis forms to cover different types of slope failure. The allocation of numerical weighting factors to relevant site features provides a relative frequency of landsliding which can be expressed as a likelihood rating. The method has been used in a wide range of conditions and has proved to be robust.
