The evaluation of seismic risk is a complex task that combine data coming from different field of expertise. The most diffused products of those studies are maps that are a graphical representation of the potential adverse outcomes that a seismic event can have over the territory at study, typically focusing on urban areas where the human activities are concentrated. Main source of concern is indeed the existing building stock, mostly composed by structures not compliant with modern seismic design criteria. The assemblage of a building inventory is pivotal for the evaluation of seismic risk. Building inventory represents how building typologies are distributed at the territorial scale and are necessarily coupled with a seismic vulnerability assessment of each class of buildings. Census-based data are usually employed as primary source for building inventory. A recent advancement is provided by the Cartis project, implemented in Italy within “Territorial themes” of Reluis consortium, financed by the Italian Civil Protection Department. This paper proposes a preliminary evaluation of the seismic risk of the town of Cassino in Southern Lazio using Census data (ISTAT) and already available fragility curves calibrated at national level.

Abstract
The evaluation of seismic risk is a complex task that combine data coming from different field of expertise. The most diffused products of those studies are maps that are a graphical representation of the potential adverse outcomes that a seismic event can have over the territory at study, typically focusing on urban areas where the human activities are concentrated. Main source of concern is indeed the existing building stock, mostly composed by structures not compliant with modern seismic design criteria. The assemblage of a building inventory is pivotal for the evaluation of seismic risk. Building inventory represents how building typologies are distributed at the territorial scale and are necessarily coupled with a seismic vulnerability assessment of each class of buildings. Census-based data are usually employed as primary source for building inventory. A recent advancement is provided by the Cartis project, implemented in Italy within “Territorial themes” of Reluis consortium, financed by the Italian Civil Protection Department. This paper proposes a preliminary evaluation of the seismic risk of the town of Cassino in Southern Lazio using Census data (ISTAT) and already available fragility curves calibrated at national level. This is intended as a Level 0 approach to be used as comparison for the ongoing CARTIS programme, when more refined data will be available.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
