This paper investigates limitations of present studies on the "slope failure hazard mapping" applying remote sensing data jointly with geographical information (i.e., causal factors). As one of the measures, an inverse analysis of slope failure triggering factors based on Structural Equation Modeling is also presented. Through the experiments on the inverse estimation of triggering factors (e.g., rainfall, earthquake, etc.) with the measurement equation, a "Trigger Factor Influence (TFI) map" has been proposed. As an application, TFI maps were produced with respect to slope failures and landslides, respectively, which might be useful for estimating unobserved triggering factors as the heuristic information.
