Assessment of Influencing Factors of Wayanad Landslides on July 30, 2024, India Using Geoinformatics

Landslides are a major natural hazard in Wayanad, Kerala, India, where steep terrain, intense monsoons, and human activities make the region highly vulnerable to landslides. Assessing the key factors influencing landslides is crucial for effective risk assessment and mitigation. This study employs geoinformatics, the Analytic Hierarchy Process (AHP), and spectral indices (NDVI, NDWI, BSI, NDMI) to analyze critical parameters, including slope, rainfall, elevation, rock type, and soil texture. By integrating remote sensing, GIS, and multi-criteria decision-making, the research determines the most influential factors contributing to landslides. The findings provide valuable insights for disaster preparedness, land-use planning, and risk reduction strategies in Wayanad.
