Table 2 Detail information about landslide events

Upper basin

Fragile lithological structure of dolomite and limestone, dense faults, very steep slopes, high rainfall intensities, dense vegetation and accelerated karstification process

Rainfall-induced rapid mass movements, rock falling, bouncing and rolling

Middle basin

Fragile lithological structure of marl, dolomite and limestone, dense faults, steep slopes, high rainfall intensity, dense vegetation, accelerated karst decomposition process and human activity including urbanization, infrastructure projects, dense slope cultivation and tourism activity

Rock falls and sliding and debris and mud flows

Lower basin

Fragile lithological structure of limestone and sandstone, gentle slopes, moderate rainfall intensities and human activity including urban expansion, infrastructure projects, floodplain farming and tourism activity

Shallow landslides and debris and mud flows
