| dc.description.abstract | A risk assessment methodology is developed to analyse the impact of natural hazards on cultural heritage objects. The methodology involves both qualitative and quantitative risk analysis approaches. In the qualitative risk analysis, probability and consequence classes based on NS 5815 are used. Probability classes are assigned to hazard events, while consequence classes are assigned to cultural heritage objects. A risk matrix is then generated to identify objects that are most vulnerable to high-risk hazards.
The quantitative risk analysis aims to quantify the impact of natural hazards on heritage objects. It introduces the concept of Heritage Loss (HL), which provides a quantitative estimate of the expected physical loss of a cultural heritage object resulting from natural or other hazards. The quantitative risk analysis stage builds upon the findings of the qualitative risk analysis by establishing a link between risk classes and numerical probabilities, as well as estimating the potential heritage loss.
To facilitate the implementation of this risk assessment methodology, a flexible Excel tool has been developed. This tool allows for efficient and customizable risk assessment based on the inputs provided. | |
