Resumen
This article proposes a multidisciplinary approach for the assessment of seismic damage from the perspective of conservation and prevention. A comparison of the state of damage has been carried out in a case study, St. Salvatore church in Acquapagana (MC), as an example of church, which underwent two important seismic events in the Central Italy area, the 1997 and the 2016 earthquakes. The comparison of the state of damage passes through the following stages: (a) the territorial seismic overview; (b) the historical description and material analysis; (c) the identification of macro-elements with activated damage mechanisms; (d) the comparison between the two seismic events both from a territorial- and building-scale perspective. This work puts together the archived and the on-site survey data with those elaborated starting from seismogenic information, available from the National Seismological Institute, and it provides a strategy also for other similar conditions. This work is to be considered a contribution to a wider study that could be carried out in the areas hit by the 2016 earthquake. It could also represent a way to collect documentation in the post-earthquake phase, improving the effectiveness of procedures currently applied to the first level of damage assessment.
