Human-Induced Landslides: Toward the Analysis of Anthropogenic Changes of the Slope Environment

Human-Induced Landslides (HIL) refer to landslide events that are directly triggered or partially aggravated by anthropic activities. Most of them are the results of anthropogenic factors such as modification of the topography, change of the water circulations, land use changes, ageing of infrastructure, etc. Seven types of changes induced by human actions that could increase the landslide hazard are distinguished in this paper. These are not mutually exclusive. Most of the case studies presented in this paper are complex and environmental changes that affect landslides stability are often not taken into account that could lead sometimes to an underestimation of landslide hazard. The paper proposes seven guiding questions about the future changes of the environment and linkages with slope stability over time. These questions provide a conceptual model for which a strong scientific basis does not currently exist.
