As part of the MYRIAD-EU project (2021–2025), a suite of innovative multi-hazard and multi-risk tools has been developed to address both EU-scale and pilot-scale analyses, supporting proof-of-concept applications across multiple sectors. The associated open software package incorporates five key components designed to enhance risk assessment and decision-making for sectors such as Finance, Tourism, Food/Agriculture, Infrastructure, Energy, and Ecosystems.
The Exposure-at-Risk Calculator enables probabilistic, historic, and stochastic event overlaps using the large array of hazard sets created in EU projects including MYRIAD-EU by linking sectoral exposure footprints to calculate overlapping exposure-at-risk and their associated probabilities for specific thresholds. This tool leverages the open hazard and exposure datasets hosted on platforms such as Zenodo and the MYRIAD website.
Complementing this, the Multi-Hazard and Risk Scenario Calculator evaluates direct and indirect risks for current and future scenarios, integrating climate and socioeconomic data. Notable applications include overlapping earthquake and flood scenarios in the Danube region, enabling comprehensive risk assessments for complex hazard interactions.
A Multi-Vulnerability Curve Editor and Database allows users to view and contribute sectoral damage functions and dynamic vulnerability data. Examples include vulnerability dynamics for multi-hazard scenarios and heatwave mortality functions derived from MYRIAD-EU research. Additionally, the Multi-Risk Index QGIS Plugin supports quantitative and qualitative risk analyses at the NUTS3 level across Europe or other selected regions. The plugin’s adjustable weighting system facilitates the integration of multi-hazard scenarios into risk metrics and indicators such as for the tourism sector or looking at financial indirect losses after events.
The Canary Islands case study uses the full integrated approach of MYRIAD-EU, focusing on tourism-sector resilience under multi-hazard conditions, such as volcanic eruptions combined with drought and climate/socioeconomic changes out to 2050. The study combines quantitative results with semi-quantitative baseline resilience indices with qualitative resilience scorecards to provide actionable insights for tourism destination management.
Scheduled for release in 2025, the software is being developed collaboratively with MYRIAD-EU partners. A comprehensive user interface and documentation will guide users in selecting appropriate tools for specific locations and multi-sector, multi-risk problems, ensuring applicability across diverse scenarios and scales.
