Mapping: Inventories, Susceptibility, Hazard and Risk

In this chapter we briefly introduce and review the interrelated concepts of mapping landslide inventories, susceptibility, hazard and risk. We emphasize the importance of extensive metadata in the characterization of landslides stressing the need for spatial information, type, abundance, age, triggering mechanism, failure parameters (slope angle, material, etc.) and volume data as basic properties of any proper inventory. Concomitantly we comment on the representation of these data in map form via scale and symbology. We examine the differences between landslide susceptibility and hazard mapping, commenting on a few of the better known qualitative (heuristic) and quantitative (statistical-probabilistic) methods of analysis. Added attention is given to a comparison between bivariate and multivariate statistical approaches. Finally we refer to the important but difficult task of addressing landslide risk, implicating the inherent relationship of landslide hazard, exposure and vulnerability. Additionally, quantitative and qualitative approaches to risk assessment and mapping are briefly discussed. Moreover, we highlight the need for more extensive hazard and risk mapping, as well as for the application of harmonized, comparable approaches to susceptibility, hazard and risk assessment where possible. The first part of this chapter provides the prelude to a number of presentations which individually deal with topics already discussed. The extended abstracts that follow represent those presentations which can provide good case study examples of relevant issues in mapping landslide inventories, susceptibility, hazard and risk.
