Definitions

Definitions for terms used in landslide zoning and risk management are given in Appendix A. These definitions are based on IUGS (1997), with some amendments in matters of detail based on internationally adopted definitions prepared by The International Society of Soil Mechanics and Geotechnical Engineering (ISSMGE) Technical Committee 32. These definitions should be used for all zoning, reports and land use planning documents, and it is recommended that the definitions are attached to these documents so there is no misunderstanding of the terms.

Definitions of the main terms are:

• Landslide. The movement of a mass of rock, debris, or earth (soil) down a slope. • Active landslide. A landslide that is currently moving; it may be a first-time movement or a reactivation. • Reactivated landslide. A landslide that is again active after being inactive • Landslide inventory. An inventory of the location, classification, volume, activity, date of occurrence and other characteristics of landslides in an area. • Landslide susceptibility. A quantitative or qualitative assessment of the classification, volume (or area), and spatial distribution of landslides which exist or potentially may occur in an area. Susceptibility may also include a description of the velocity and intensity of the existing or potential landsliding. Although it is expected that landsliding will occur more frequently in the most susceptible areas, in the susceptibility analysis, time frame is explicitly not taken into account.

Landslide susceptibility includes landslides which have their source in the area, or may have their source outside the area but may travel onto or regress into the area.
