This section reviews the current methodologies that are used for the assessment of the rockfall susceptibility, hazard and risk. Emphasis is given on quantitative methods although qualitative ones are also discussed. The different methodologies are presented with respect to their application scales (regional, local or site-specific). Highlight is given to recent advances, especially involving the consideration of the magnitude of the events and the intensity of the phenomena at selected locations as well as the incorporation of a quantitative vulnerability into the risk equation.
