To date, several multilevel methodologies for seismic risk assessment and management of cultural heritage are available in the literature. These tools enable knowledge and analysis of historic buildings for proper maintenance and interventions design.

In this work, the multilevel methodologies in the literature are first briefly analyzed and compared. Afterwards, the parameters involved in the seismic risk assessment of existing masonry churches are identified and a new form suitable for the data collection of hazard, vulnerability and exposure information is proposed. In this form the information is filtered according to the required level of analysis, with the aim of developing a new methodology for risk assessment. The amount of information is increasing, useful for qualitative territorial analyses up to detailed analyses requiring the use of refined models.

Finally, this model form is applied to a selected case study to test the validity of the tool.

Key words: multilevel analysis, seismic risk, cultural heritage, existing masonry churches
