Overview of input data for Quantitative Risk Analysis from the consequences of geohazard

The aim of landslide risk assessment is to determine the spatial and temporal probability of landslides in a particular area, together with their mode of spread, size and intensity. Risk analysis must take into account possible breakdown mechanisms. Regardless of the work scale, the hazard assessment must define the time frame for the occurrence of potential types of landslides and their intensities at the considered location. The time occurrence of a landslide is normally expressed in terms of frequency, return period or probability overrun. The return period is the inverse annual probability return and refers to the average time interval in which an event of a certain magnitude is expected to occur. This paper provides an overview of the input data required for the assessment and quantitative risk analysis related to the occurrence of the most common geohazards in practice (landslides, shallow landslides, debris flows and large slow landslides). For a clearer overview, their importance in the assessment of sensitivity and hazards for different landslide mechanisms is given. At the same time, methods for quantitative risk analysis of landslide have been proposed.
