Challenges of LSLHM project (00:08:22)
Challenge I: fast-moving or slow-moving landslide? (00:08:29)
By using landslide morphology, 9230 potential LSL were identified (00:09:02)
By using landslide morphology, 9230 potential LSL were identified (00:09:17)
Solution (00:10:07)
Challenge II: LSL hazard mapping (00:10:54)
Challenge: Entire or Partial landslide (00:10:59)
Empirical Method (00:11:36)
Solution (00:11:57)
Challenge III: Red alert How to decide threshold of red alert? (00:12:14)
Threshold of Yellow alert is almost ready, which depend on the rainfall information as follows (00:12:28)
Safety Factor of Land Slope (00:13:33)
The meaning of safety factor drop(1-Fs) (00:14:17)
Challenge IV: How to lift the red alert? (00:15:36)
Challenge IV: How to lift the red alert? (00:15:58)
