Abstract
Landslide susceptibility and hazard zoning, and to a lesser extent, landslide risk zoning, have experienced extensive development during the last few decades. Most of these zoning studies are qualitative in nature, although more recently there have been examples of quantifying the hazard by assigning an annual probability (frequency) to the potential landslides and quantifying the risks for existing development. Unfortunately, among countries and even within any one country there is seldom uniformity in terminology and the results of the landslide zoning are often not precisely defined, and susceptibility, hazard and risk are often used interchangeably in landslide zoning maps. There is an increasing need for quantitative risk management principles that require the use quantitative methods for landslide hazard and risk zoning. This allows one to compare them with other hazards and risks, and with loss of life tolerance criteria. The guidelines provide: Definitions and terminology for use internationally. Description of the types and levels of landslide zoning. Guidance on where landslide zoning and land use planning are necessary to account for landslides. Definitions of levels of zoning and suggested scales for zoning maps taking into account the needs and objectives of land use planners and regulators and the purpose of the zoning. Guidance on the information required for different levels of zoning taking account the various types of landslides. Guidance on the reliability, validity and limitations of the methods. The guideline is intended for use by local, state and national government officials, geotechnical professionals, land use planners, and project managers.
