Integrated AI Framework
This study integrated Artificial Neural Networks (ANN), Transfer Learning (TL), Interpretable Machine Learning (IML) via SHAP values and Partial Dependence Plots (PDP), and qualitative Geomorphic Plausibility assessment. This multi-faceted approach aims to produce robust and understandable landslide susceptibility maps.
A source ANN model was trained on a data-rich area (Arjosari), then fine-tuned via TL for a data-scarce target area (Kebonagung). This strategy is designed to overcome the common challenge of insufficient landslide inventory data in critical regions.
The workflow focused on comprehensive validation, including quantitative metrics (AUC) and qualitative assessment (geomorphic plausibility) to ensure physically meaningful results that align with real-world terrain behavior.
Performance and Spatial Patterns
The Transfer Learning model significantly outperformed the baseline model, achieving an AUC test score of 0.97 compared to 0.83, demonstrating strong potential for transferability in data-scarce regions and high accuracy.
Slope, elevation, aspect, and distance to stream were identified as the most influential landslide conditioning factors, directly impacting susceptibility across the study areas.
Geomorphic plausibility assessment confirmed that high susceptibility zones clustered in mid-slopes and concave-convex transitions, aligning with terrain behavior. Conversely, low susceptibility was observed in steep rocky slopes (>40°) and flat areas.
Unveiling Model Decisions with XAI
SHAP values, permutation importance, and partial dependence plots revealed the direction and magnitude of feature influence, showing how factors like slope and elevation contribute to predictions for specific landslide instances.
Curvature and terrain indices, while less impactful directly, showed significant contributions through interactions with other features, highlighting the need for a multifaceted interpretation approach to fully understand complex relationships.
This approach addresses the "black-box" nature of traditional ML models, providing transparency for better risk planning, stakeholder communication, and science-based policy development.
Roadmap for Enhanced Accuracy
Limitations include potential biases from event-based landslide inventories, the subjective nature of some geomorphic plausibility rules, and challenges in generalizing models to geologically diverse areas.
Future research could expand conditioning factors to include dynamic triggers like rainfall and soil properties, use high-resolution or multi-resolution data fusion techniques to mitigate resampling uncertainties.
Integrating field-based validation, expert judgment, and focus group discussions would further enhance the practical applicability and credibility of the susceptibility maps for local planning and disaster mitigation efforts.

Case Study: Landslide Susceptibility in Pacitan, East Java
The Pacitan Regency, a region with rugged topography and frequent landslides due to tropical cyclones and monsoons, served as the focus.
The study addressed the critical challenge of data scarcity for accurate landslide susceptibility mapping in this high-risk area, leveraging Transfer Learning to overcome this limitation.
The developed Transfer Learning model successfully produced high-resolution (5m) LSS maps, identifying 43.4% of Kebonagung as moderately to very highly susceptible, providing crucial data for disaster mitigation and spatial planning.
Model interpretation confirmed that slope, elevation, aspect, and distance to stream are key local drivers of landslide susceptibility in Pacitan, offering clear insights for targeted interventions.
