*5.3. Accuracy Validation*

Figure 8 shows that over 60% of the landslides had occurred in the extremely high (31.53%, 134 of 425) and high (29.88%, 127 of 425) landslide susceptibility areas, respectively. Less than 10% of the total landslides occurred in the area mapped as low (8.24%, 35 of 425) and very low (1.65%, 7 of 425) susceptibility levels. In line with the procedures described in Section 4.5, the ROC curve was drawn as shown in Figure 9, and the AUC value was 0.86.
