Short summary
The difference in susceptibility might lead to a difference in warning threshold for rainfall-induced landslides. Here we divided slope units into three susceptibility levels and established their thresholds separately. It was found that the threshold values gradually increased as the susceptibility decreased for the same alert level. This showed that classifying susceptibility and establishing thresholds separately might provide refined thresholds for disaster prevention.
