Rainfall-triggered landslides, anthropogenic hazards, and mitigation strategies M. C. Larsen U.S. Geological Survey, 436 National Center, Reston, VA 20192, USA
Abstract. Rainfall-triggered landslides are part of a
natural process of hillslope erosion that can result in catastrophic loss of
life and extensive property damage in mountainous, densely populated areas.
As global population expansion on or near steep hillslopes continues, the
human and economic costs associated with landslides will increase. Landslide
hazard mitigation strategies generally involve hazard assessment mapping,
warning systems, control structures, and regional landslide planning and
policy development. To be sustainable, hazard mitigation requires that
management of natural resources is closely connected to local economic and
social interests. A successful strategy is dependent on a combination of
multi-disciplinary scientific and engineering approaches, and the political
will to take action at the local community to national scale.
