Multi-risk assessment in transboundary areas: A framework for harmonized evaluation considering seismic and flood risks

This paper presents the approach for multi-risk assessment proposed within BORIS project (Cross BOrder RISk assessment for increased prevention and preparedness in Europe). Focusing on seismic and flood risks, this project aims to develop a shared methodology for cross-border multi-risk assessment in Europe. Adopting a single-layer multi-risk approach, each risk is assessed through independent analysis, but the procedures for risk assessment are harmonised in order to ensure their comparability. Also, the issue of transboundary assessment of single risks is addressed. The proposed methodology is applied in two regions in the cross-border area between Italy, Slovenia and Austria, demonstrating the usefulness of the BORIS approach for multi-risk comparison and ranking.
