The research status associated with landslide time prediction was comprehensively reviewed. The current approach employed in the time of slope failure prediction were generalized as regression models based on empirical formula and mathematical theory respectively. In addition, the applicability of each model and method as well as the relevant prediction criterion and warning threshold were briefly analyzed. In order to acquire more accurate results, it is indispensable to establish an approach that can describe the evolution process of landslide and the mechanism of failure on the basis of in-depth study of landslide types, geological characteristics, and deformation characteristics combined with appropriate criteria and early warning threshold.
