Short summary
Short summary
We applied the Maximum Entropy model to characterise multi-hazard scenarios in a karst environment, focusing on flood-triggered sinkholes in Val d'Orléans, France. Karst terrains as multi-hazard forming areas, have received little attention in multi-hazard literature. Our study developed a multi-hazard susceptibility map to forecast the spatial distribution of these hazards. The findings improve understanding of hazard interactions and demonstrate the model's utility in multi-hazard analysis.

Short summary
The 2025 California wildfires revealed persistent gaps between what we know about reducing disaster risk and what communities actually do. Limited awareness, weak resources, misaligned incentives, and complex rules leave people exposed. Similar patterns appear in floods, earthquakes and other disasters worldwide, highlighting the urgent need for stronger institutions, clearer policies, and active community engagement to build fair, practical, and lasting resilience.

Short summary
The article provides a comparison of a standard (deterministic) risk assessment approach for roads exposed to a multi-hazard environment with a probabilistic risk analysis method to show the potential bias in the results. A probabilistic approach enables the quantification of epistemic uncertainty and uses probability distributions to characterize data uncertainty of the input variables, while a deterministic computation uses single values with discrete values without uncertainty representation.
The article provides a comparison of a standard (deterministic) risk assessment approach for...
