### Hazard Assessment  
#### 3.2.1 Qualitative Evaluation  
The qualitative hazard distribution highlights the presence of 755 census tracts characterized by single hazard (flood or landslide) and 127 covered by multi-hazard (MH)

Table 5: Table showing the 13 municipalities belonging to the study area with the number of inhabitants registered in 2021 and the number of census tracts. sectors (flood + landslide). Apart from Policoro, all municipalities are characterized by single-hazard and MH scenarios. In the first case, 470 census tracts are intersected by flood hazard (FH), mostly located within the Ionian coast in the municipalities of Bernalda, Pisticci, Scanzano Jonico, Policoro, Rotondella, and Nova Siri (Figures 5 and 6), and along the Bradano river within the municipality of Montescaglioso (Figure 6b). On the contrary, 287 census tracts are affected by landslide hazard (LH) in the municipalities of Tursi, Pisticci, Pomario, Montescaglioso, Montalbano Jonico, and Craco (Figure 5). An extended territory characterized by the MH scenario is located in the central and southern sectors of the study area across the municipalities of Pisticci, Montalbano Jonico, Scanzano Jonico, Tursi, Rotondella, Nova Siri, Colobraro, and Valsinni (Figure 6c,d). According to Figures 5 and 6, almost all census tracts belonging to the FH scenario are associated with FH3 (417), whereas 31 census tracts are related to FH2 and 22 are related to FH1, especially in the municipality of Policoro (Figure 6d). As shown in Figure 6, scenarios with more variety are highlighted in census tracts affected by LH and MH. Starting from the northern sector (Figure 6c), the central part of Montescaglioso, where the town center is located, is represented by 47 census tracts classified as having LH with scenarios corresponding to LH3, LH4, LH5, LH8, LH9, and LH12, whereas 5 census tracts, located in the north-eastern part of the municipality, are characterized by them H4, MH7, MH9, MH10, and MH12 scenarios. Along the border with this municipality, Bernalda only shows 2 census tracts associated with MH (MH5 and MH8), while it shows 34 census tracts associated with LH2, LH4, LH5, LH7, LH8, and LH12, also corresponding to the town center. In the municipality of Pomario, 34 census tracts are found in LH2, LH3 LH4, LH5, LH7, LH9, LH10, LH11, LH12, and LH13 scenarios, while 9 census tracts fall in MH5, MH9, MH11, MH13, and MH14 scenarios. The town center is also located in an LH area in this case. Moving to the central sector of the study area (Figure 6c), 68 census tracts are covered by LH1, LH2, LH3, LH4, LH5, LH8, LH11, and LH13 scenarios, and 46 are covered by the MH4, MH5, MH8, and MH14 hazard combinations within the municipality of Pisticci. Most of the census tracts located in the municipality of Craco (25) are intersected by LH2, LH3, LH4, LH5, LH7, LH9, LH10, LH11, LH12, and LH13 scenarios, whereas 15 census tracts are characterized by MH5, MH8, MH9, and MH11 scenarios.
