Table 5 Matrix used to assess the physical vulnerability of roads, harbours and heliports on Vulcano (adapted from Guobadia 2017). L, M and H indicate low, medium and high (Qualitative assessment). Numbers used for a quantitative vulnerability assessment are also indicated in the fifth column
System | Aspect parameters | Criteria for assessment | Physical vulnerability indicator | Physical vulnerability level and associated score |
