    Description: The Disruption Index is used here for the assessment of urban disruption in the Mt. Etna area after a natural disaster. The first element of the procedure is the definition of the seismic input, which is based on information about the historical seismicity and seismogenic faults. The second element is the computation of the seismic impact on the building stock and infrastructure in the region considered. Information on urban-scale vulnerability was collected and a geographic information system was used to organize the data relating to buildings and network systems (e.g., typologies, schools, strategic structures, lifelines). The central idea underlying the definition of the Disruption Index is the identification and evaluation of the impacts on a target community, considering the physical elements that contribute most to the severe disruption. The results of this study are therefore very useful for earthquake preparedness planning and for the development of strategies to minimize the risks from earthquakes. This study is a product of the European “Urban Disaster Prevention Strategies using Macroseismic Fields and Fault Sources” project (UPStrat-MAFA European project 2013).

    Description: The results of a detailed seismic microzonation study performed at Canazei (Trentino—Northern Italy) are here presented. We investigated the local seismic response of this small village using a Level 3 seismic microzonation, the most accurate according to the Italian Code of Seismic Microzonation. This method consists of gradual steps of knowledge to consider different aspects of the amplification phenomena. A multidisciplinary approach has been performed, including a local geological study, geophysical investigations, geotechnical characterization of lithologies and numerical analyses. The obtained elastic response spectra were compared to the spectra prescribed by the Italian Building Code. Our results show the geologic and geophysical subsoil heterogeneities, responsible for different local seismic responses in terms of acceleration spectra and amplification factors.
