Landslides, as a common geo-hazard, can result in huge economic losses and enormous casualties in mountainous regions of the world. Therefore, the assessment of landslide hazard and risk has become a topic of major interest for both geoscientists and engineering professionals. Firstly, the significance of rainfall-induced landslides mechanism, landslides risk assessment and risk mitigation is addressed. Secondly, this paper reviews the recent advances in geo-hazards associated with landslides from the aspects of geomechanics mechanism of rainfall-induced landslides, landslides mechanism, numerical simulation of evolution process of landslides, dynamic risk assessment and risk mitigation associated with landslides. Based on the critical review, problems in the past study of the rainfall-induced landslides are examined, and some challenge issues in rainfall-induced landslides are discussed. Finally, further research directions are suggested. It is recommended that the research on geo-hazards associated with landslides should take the dynamic process of landslides as the main line, take the geomechanics mechanism as the basis, take the landslides mechanism as the key problem, and take the landslides risk assessment as the tool. The final goal is to reduce the landslides risk as low as possible.
