Innovazione nell’analisi urbana per l’emergenza sismica - Innovation in analysing urban seismic emergency” (capitolo 4)

After a seismic event, every installation undergoes physical and functional damage, threatening many urban functions present, yet it retains certain features that becomes fundamental in confronting the emergency. These strategic functions may have been provided by a program of targeted measures, but sometimes they are inherent in the urban fabric that, over time, has become characterized by open spaces (squares, parks, gardens, car parks, etc.), wide streets, even buildings (historical or new) that are structurally capable of withstanding earthquakes and that can become strategic points of service in the emergency. In analysing free spaces, connections or the structures created for emergency management, one also generally accounts for the system interconnection among emergency facilities and the accessibility to the local context. The goal of planning an intervention system in anticipation of seismic events or the reconstruction process in the event of disasters must concern the reorganization of urban systems and the referred building, which should be considered in restoring both access systems to urban areas as well as those linked within the urban fabric, while the other side has to take care of reassembling functional, formal, infrastructural and structural buildings damaged and the possible interference with public spaces, in accordance with the urban system and construction and with the close relationship between the environment and urban landscape.
