Landslides occur in all geographic regions in response to a wide range of conditions and triggering processes that include storms, earthquakes, and human activities. In addition to direct losses, landslides also cause significant environmental damage and societal disruption. Over the past decade there has been a gradual shift away from simply relying on engineering solutions to individual landslide problems, to the use of a variety of strategies to manage the problems over a broad area. To reduce potential damage caused by landslides, one management option is the development and utilization of monitoring and warning systems. These systems should be combined with regulations aimed at minimizing the loss of lives and property damage without investing in long-term, costly projects of ground stabilization.
The session is aimed at comparing qualitative or quantitative risk estimates in different areas based on different scales. Since it is necessary to assess landslide hazard before evaluating landslide risk, contributions dealing with landslide mapping and landslide hazard assessment are welcomed. Presentations on landslide hazard and risk assessment at local, regional or national scale and in different physiographic, climatic and geological settings are solicited. Papers that provide information of the quality, the reliability and the limitation of the models are encouraged. The session's aim is to present contributions dealing with heuristic, statistical, deterministic or physical based methods and models to evaluate and compare landslide hazards and risk.
