Understanding fatal landslides at global scales: a summary of topographic, climatic, and anthropogenic perspectives

• growing demographic pressure and land use/cover changes increase frequency and impact of landslides

• recording/monitoring/analysis are essential for robust/predictive models

• human stress on slopes under extreme wheater leads to proportional increase in fatalities

• south asia most affected region because of summer monsoon

• most fatal non-seismic landslides are caused by natural factors (84,5%) rather than anthropogenic (15,5%)

• landslide concentration and fatality is highest around tropical and temperate regions (94%)

• conentration and fatality of landslides is around 20% higher in plains for anthropgenic causes and vice versa for natural causes in low/middle mountains

• mortality rate (average number of fatalities per landslide) higher for naturally triggerd landslides

• mortality rate lower for tropical and temperate regions

• landslides with many fatalities are relativly rare

• landslides are expected to inscrease due to climate change

• landslides triggered naturally may be influenced my anthropogenic factors (reduced hill stability, ...)

• natural at higher elevation, anthropogenic at lower elevation
