Integration of Geodetic Strain: A Novel Approach
This study marks the first time geodetic strain derived from GNSS measurements has been integrated into spatial earthquake probability modeling. This dynamic representation of crustal deformation proved to have a significant influence on the model's decision-making process, providing a physically grounded measure of stress accumulation. SHAP analysis confirmed that high strain rates (especially above ~80-100 ns/yr) are a critical predictor, reinforcing the elastic rebound theory and indicating areas of superior risk. This integration offers a dynamic, geophysically meaningful perspective that complements traditional static and structural indicators, enhancing the model's predictive power for seismic hazard assessment.

Explainable AI (XAI) with SHAP Analysis
The SHAP (SHapley Additive exPlanations) method was applied to the best-performing Random Forest model to interpret its predictions and quantify each feature's contribution. This approach clarifies the decisive influence of variables such as proximity to faults, peak ground acceleration (PGA), epicenter density, magnitude density, and geodetic strain on the model's decision-making process. SHAP dependence plots revealed specific value thresholds where contributions become positive or negative, confirming that the model's decision logic aligns well with geophysical principles. This transparency moves beyond 'black box' models, strengthening geoscientific interpretability.
Practical Applications for Seismic Hazard Assessment
The resulting Earthquake Spatial Probability Map (ESPM), generated using the RF model, clearly delineates high-probability zones along major active fault systems (NAFZ, EAFZ, WAEP) and other tectonically complex regions across Türkiye. This interpretable framework supports critical disaster management activities:
- Urban Planning: Guides objective prioritization for seismic strengthening and reconstruction in vulnerable building stock by identifying high-risk areas.
- Emergency Response: Supports strategic location of logistical hubs, temporary shelters, and emergency routes to reduce response times.
- Infrastructure Siting: Informs decisions on siting hospitals, energy facilities, and transport hubs, emphasizing geologically stable sites and accounting for ground amplification effects (lithology showed minimal positive influence).
The SHAP-based interpretability ensures that high-risk zones are identified with their underlying causes, promoting rational, evidence-based, and accountable decision-making in earthquake risk management strategies, which can be transferred to other similar tectonic environments.
