WB3 –Landslide Risk ManagementLandslide Risk Mitigation: Early warningMountain RisksResearch Training NetworkLandslides are complexphenomena:Different mechanisms involved (fall,sliding, flowage,...)Different triggers: rainfall,earthquakes, volcanic eruptions,erosion, etcDifferent stages of development:pre-failure, failure, post-failure &reactivationDifferent post failure behaviour:acceleration due to reduction of thesoil/rock strength (i.e. brittle soils,dilative soils) or stabilizationSource: USGSMOUNTAIN RISKS: Mid-term Meeting, Diablerets, 26-27 June 2009
