Multi-Hazards scenarios

Please select the number of hazard scenarios. Locate the place of interaction of each event and select the level of interaction: 1(Low), 2(Medium), 3(High)

💡 Recommendation

All project partners (INERIS, CERTH, GIG, THGA, PPC, and SRK) collaborated to assess the interactions between Mining hazards and Natural Hazards. It is recommended to use the following interaction matrix when developing each scenario:

Interaction Matrix for Post-mining Hazards

Expose elements

Land Use/ Land Cover

The Element at Risk (EAR) to be evaluated comes from the Land Use and Land Cover layer retrive from ESRI 2024 LU/LC pre-classified dataset .

To follow the calculation of the EAR factor, define level of significance of each element:

Vulnerability

Vulnerability Index(VI)

The DSS works with statistical data from city or regional level for the calculation of vulnerability indicators and, subsequently, the Vulnerability Index.

The following 4 macro indicators are used to assess vulnerability: Socioeconomic Status, Household Composition, Environment, and Overall Infrastructure. Each macro indicator is derived from several measurable factors:

• Socioeconomic Status is determined by the Unemployment Rate (%) and GDP per capita (€), reflecting the economic well-being and labor market conditions of the population.
• Household Composition considers the proportion of Population under 18 years old and over 64 years old, indicating demographic dependency levels and potential vulnerability of age groups.
• Environment integrates Population Density (people/km²), Settlement Area (%), and Agricultural Areas (%), providing insights into land use patterns, urbanization pressure, and exposure to environmental risks.
• Overall Infrastructure is evaluated using Building Age, Building Material, Geometry (average or predominant building types), and the percentage of Traffic Area, offering a picture of construction practices and accessibility.
