Natural Hazards
Exposure to natural hazards according to the European Commission's INFORM index, from 0 (very low) to 10 (very high), overall and for each type of hazard.
Overall Risk Index
This overall score combines hazard exposure with the vulnerability of the population (3.0 out of 10) and the lack of coping capacity (3.0 out of 10). A highly exposed but well-prepared country therefore gets a low overall score.
