Advanced Landslide Inventory & Risk Modeling
- Developed a spatial algorithm-based automatic labeling method to enhance mass-wasting inventories, distinguishing events into four types based on movement behavior.
- Achieved 82-85% consistency with manual labeling, with 59% for debris floods, validated using the July 2023 Beijing extreme precipitation event.
- Applied the method to a larger inventory, identifying failure types and delineating source areas.
- Quantified factor contributions for different mass-wasting types using Shapley Additive Explanations (SHAP), revealing type-specific controls.
- Enhances inventory quality without large labeled datasets, providing deeper insights into rainfall, terrain, and lithology contributions to mass wasting.

Beijing Extreme Precipitation Event (July 2023)
The proposed method was validated using data from the July 2023 extreme precipitation event in Beijing, China, which recorded the highest rainfall in the region since 1963. This event triggered tens of thousands of mass-wasting events, making it an ideal real-world scenario for testing.
Manual interpretation of a subset yielded 1309 mass-wasting events, with an overall consistency of 82-85% between manual and automatic labeling for hillslope slides, hillslope flows, and converging flows. Debris floods showed 59% consistency.
The method successfully identified 10,160 hillslope slides, 4,717 hillslope flows, and 408 debris floods across the complete inventory, demonstrating its scalability and effectiveness in real-world disaster response and analysis.
