“…This has been defined by several authors in terms of both societal vulnerability (Glade, 2003) and physical vulnerability (Uzielli et al, 2008). The latter is a scenario-specific parameter defined as "the degree of loss to a given element or a set of elements within the area affected by the hazard" (ISSMGE TC32, 2004).…”

“…When dealing with natural hazards, a risk-based approach to countermeasure design should be used to account for the uncertainties related to frequency, probability of impact on exposed elements, and vulnerability (Straub and Schubert, 2008;Uzielli et al, 2008). Moreover, rockfalls are rare and strongly spatially distributed processes, characterised by complex dynamics and interaction with structures.…”

Abstract. Rockfall risk analysis for mitigation action design requires evaluating the probability of rockfall events, the spatial probability and intensity of impacts on structures, their vulnerability, and the related expected costs for different scenarios. These tasks were integrated in a quantitative risk assessment procedure supported by 3D rockfall numerical modelling performed by the original code HY-STONE. The case study of Fiumelatte (Varenna, Italy), where a large rockfall in November 2004 resulted in 2 casualties, destruction of several buildings and damage to transportation corridors, is discussed. The numerical model was calibrated by a back analysis of the 2004 event, and then run for the whole area at risk by considering scenarios without protection (S0), with a provisional embankment (S1), and with a series of long-term protection embankments (S2). Computed impact energy and observed damage for each building impacted in 2004 were combined to establish an empirical vulnerability function, according to which the expected degree of loss for each element at risk was computed. Finally, costs and benefits associated to different protection scenarios were estimated, in order to assess both the technical performance and the cost efficiency of different mitigation options.

“…This type of detailed structural analysis of buildings has been also proposed by Spence et al (2004) in the case of the Vesuvius pyroclastic flows. Conversely, Uzielli et al (2008) classified the elements at risk with a system of 'susceptibility factors' for buildings and people.…”

The detection of active movements that could threat the infrastructures and the population is one of the main priorities of the risk management chain. Interferometric Synthetic Aperture Radar (InSAR) techniques represent one of the most useful answers to this task; however, it is difficult to manage the huge amount of information derived from the interferometric analysis. In this work, we present a procedure for deriving impact assessment maps, over a regional test site, using as starting point Sentinel-1 SAR (Synthetic Aperture Radar) images and a catalogue of elements at risk that acts as a second input of the methodology. We applied the proposed approach, named as Vulnerable Elements Activity Maps (VEAM), to the islands of Gran Canaria, La Gomera and Tenerife (Spain), where we analysed SAR images covering the time interval November 2014-September 2016. The methodology, meant to be a powerful tool for reducing the time needed for a complete analysis of a full stack of InSAR data, is ideally suited for Civil Protection Authorities. The application of the methodology allowed to detect 108 areas affected by active deformation that are threatening one or more elements at risk in 25 municipalities of the three islands.

“…Leone et al (1996) presented a general method for quantitative evaluation of building vulnerability to mass movements. Heinimann (1999) classified the vulnerability of structures according to their typology, proposing six categories, to which Uzielli et al (2008) attributed certain vulnerability values based on empirical criteria. The Australian Geological Survey Organisation (AGSO 2001) suggested a simple classification of building vulnerability with a difference between rockfalls on slopes steeper than 25°(vulnerability value equal to 1) and small rockfalls (vulnerability value equal to 0.25).…”

A procedure is presented for investigating the response of reinforced concrete buildings to rockfall impact. The method considers a single rock hit on the basement columns, and it includes four steps: (a) calculation of the probability of a rock impact on a member of the load-bearing system, taking into account the block size and the design of the structure; (b) evaluation of the response of one or more structural elements to the hit based on element capacity; (c) in the case of structural element failure, assessment of the robustness of the whole structural system, calculating the potential for progressive collapse; and (d) calculation of a damage index (DI), which is the ratio of structural elements that fail to the total number of structural elements. The proposed method is applied to a reinforced concrete building for a range of rockfall paths and intensities. The analysis has been carried out for a 2-m-diameter block and velocities< 3.5 m/s. The possible damage range is found to be highly variable, with DI values ranging from 0.01 to 1 depending on the impact location and block velocity.
