More than half a century later, the damaged settlement is still largely recognisable and has been experiencing a new season of interest for some years now, both from the local community and various kinds of outsiders who imagine economic spin-offs of an uncertain nature in its enhancement. The research we present questions the chance of survival for the settlement, forgotten for decades, in the context of interventions aimed at its reuse. Alternative strategies are discussed: on the one hand, that of bringing the ancient centre back to life, even in part, with a limited inclusion of collective functions and without claiming to inhabit it again; on the other hand, and in the authors’ opinion, more likely, that of reusing the ruins as an archaeological area preserving their memory i...

Through the summary analysis of the legislation adopted for the reconstruction process after the Belice (1968) and Friuli (1976) earthquakes, this contribution aims at investigating the peculiarities of the different intervention strategies adopted for the conservation of the traditional masonry buildings and the historical built landscape – to which they belong – recognised as the essential component of the Italian cultural heritage. Specifically, the 1968 and 1976 earthquakes provided an opportunity to enhance the cultural debate on the approach to the towns destroyed by seismic events and initiated an ongoing process which progressively m...

In the climate and in the context of an increasing seismic risk in the center-northern part of Italy, seismic vulnerability can become the determinant cause of the final abandonment of a small town. In some Italian regions, as well as Emilia Romagna, municipalities are implementing seismic vulnerability reduction policies based on the Emergency Limit Condition that has become a basic reference for ordinary land planning. This study proposes a valuation planning approach to the seismic vulnerability reduction carried out within the general planning framework concerning the Faentina Union, a group of five small towns located in the southwestern part of the Province of Ravenna, Italy. The approach consists of three main stages: knowledge-the typological, constructive and technological description of the buildings specifically concerning their vulnerability degree; interpretation-the analyses aimed to outline a range of hypotheses about the damages in case of seism; planning-identifying the works intended to definitely reduce the vulnerability of the buildings. This stage includes a cost modelling tools aimed at outlining the trade-off between the extension and the intensity of the vulnerability reduction works, given the budget.

In the climate of the centre-northern part of Italy, and in the context of the recent concentration of a high number of earthquakes in that area, seismic vulnerability can become the determinant cause of the final abandonment of a small town. In some Italian regions, as well as in Emilia Romagna, municipalities are implementing seismic vulnerability reduction policies based on the Emergency Limit Condition, which has become a basic point of reference for ordinary land planning. This study proposes an approach to seismic vulnerability reduction based on valuation planning for implementation within the general planning framework of the Faentina Union, a group of five small towns located in the southwestern part of the Province of Ravenna, Italy. This approach consists of three main stages: knowledge-the typological, constructive, and technological descriptions of the buildings, specifically concerning their degree of vulnerability; interpretation-analysis with the aim of outlining a range of hypotheses with respect to damage in case of a prospective earthquake; and planning-the identification of the courses of action intended to meaningfully reduce the vulnerability of buildings. This stage includes a cost modelling tool aimed at defining the trade-off between the extension and the intensity of the vulnerability reduction works, given the budget.
