Based on the hazard susceptibility maps, we verify and discuss the occurrence of landslides on the two routes using the landslide inventories during 2015–2017. The results show that: (1) at 129 locations along route 8, 314 landslides have occurred, the 158 landslides that have occurred at the other 79 locations are not shown on the hazard susceptibility maps; (2) 256 landslides have occurred along route 9 in the past three years. 181 landslides have occurred at 49 high-potential hazard locations; 26 landslides have occurred at 15 moderate-potential hazard locations; 46 landslides have occurred at 12 low- potential hazard locations; 3 landslides have occurred at 2 very low- potential hazard locations. From the results, we suggest further investigations is required of the hazard susceptibility maps of the Provincial highway routes 8 and 9. |
