This study presents a machine learning-based framework to predict the magnitude of earthquakes using geospatial and temporal features. A dataset of seismic events from 2010 to 2023 was compiled from public sources, covering Thailand and neighboring regions. After data cleaning and feature engineering, three regression models - Linear Regression, Random Forest, and XGBoost were trained and evaluated using standard metrics: MAE, RMSE, R², and Explained Variance Score. The results demonstrate that XGBoost significantly outperforms the other models, achieving the lowest prediction errors and highest explanatory power. Feature importance analysis confirms the influence of spatial variables such as depth and latitude over temporal features. Residual analysis further supports the reliability and stability of tree-based models, particularly in handling nonlinear relationships. This research highlights the practical applicability of machine learning for earthquake risk mitigation and provides a foundation for integrating predictive models into urban planning, early-warning systems, and disaster resilience strategies in Thailand.MathematicsComputer SciencePhysics and AstronomyEngineeringConference PaperSCOPUS10.1109/RI2C67120.2025.112828102-s2.0-105031752720
