In the test carried out for the Sisma project in the historical centre of Forlì, the method for the seismic urban vulnerability assessment defined by the Emilia-Romagna region since 1990 and until now tested just on the smaller villages, has been used in order to verify its applicability to a settlement with more than 108.000 inhabitants. In this method, urban risk is not only connected to seismic regional hazard, to exposure and vulnerability of buildings and networks, but also to the internal organisation of functional systems (the sub-systems which are most important for urban quality and the sub-systems for emergency service) and to their levels of performance. Not only the physical damages are taken into account, but also the consequent modification of spatial and organisational patterns, as well as the modification of the flow of resources which characterize the urban system.
