Abstract: The escalation of geo-hazards, particularly landslides, has become a pressing concern, exacerbated by both natural factors and human activities. The frequency of rainfall-triggered landslides in mountainous regions is surging, posing imminent threats to lives and infrastructure. Jammu and Kashmir witness this peril throughout the year, affecting millions. This study focuses on creating a landslide susceptibility map for District Doda, employing a multi-method approach. A comparative analysis of multi-criteria decision method-analytical hierarchy process (AHP) and Shannon information entropy (SIE) determines their efficacy. The inventory, comprising 250 landslides, incorporates nine conditioning factors. AHP designates 91% of the area as very high or highly susceptible, while SIE identifies 46.49% as vulnerable. Area under curve (AUC) values of 0.898 and 0.976 for AHP and SIE, respectively, underscore the latter's superior predictive capability. This study is instrumental in aiding stakeholders with decision-making, land-use planning, and formulating effective mitigation strategies.
