GNGTS 2018 S essione 2.2 485 Tramite le formule (1), (2) e (3) e il fattore di amplificazione topografico si è calcolato il fattore di amplificazione relative alla media dei sette accelerogrammi utilizzati (Tab. 2). I valori di FA confermano che il fenomeno di amplificazione in superficie rispetto al moto alla base è assai significativo.

The research presented in this paper springs from a collaboration between the “Dipartimento di Ingegneria Civile, Edile–Architettura e Ambientale” (DICEAA) of the University of L’Aquila and the “Servizio Prevenzione dei Rischi di Protezione Civile” of the Regione Abruzzo. Such a collaboration is focused on the seismic risk reduction and prevention. Specifically, the collaboration promotes the research and development of investigations and actions aimed at preventing the seismic risk in all the region. The central issues of the research are the “Microzonazione Sismica (MZS) Levels 1 and 3”, the “Condizione Limite per l’Emergenza comunale (CLE) e Intercomunale (CLE-I)”, and the reduction of the seismic vulnerability of strategic structures, three issues that were dealt with jointly by the National Seismic Prevention Program funded by the Law 77/2009, art. 11 (Dolce, 2012).On these topics, DICEAA and “Servizio Prevenzione dei Rischi di Protezione Civile” started an experimental program that takes the city of Sulmona (AQ) as a case study (ITC-RegAbr 2007). This paper summarizes the initial results of this interdisciplinary research and has as main topic the “seismic prevention”. In particular: i ) the risk reduction and the consequent increase in the resilience of the territorial and urban contexts, and of the built environment; ii ) the pre-disaster planning and the consequent proposal of new management procedures for the interventions of the Protezione Civile that account for the city planning aspect of the issue. Further research steps will focus on related topics such as: i ) the coherent merging of plans coming from different institutions and
