Slope stability is very important for sustainable development in mining, civil engineering, and urban planning, especially in landslide-prone areas like the Western Ghats of Maharashtra. It ensures the safe design and assessment of slopes in natural and man-made environments, helping to reduce risks and protect vulnerable communities. This is particularly crucial in Raigad District, where steep terrain and heavy monsoon rains increase the chances of landslides. Therefore, detailed geotechnical studies and slope stability analyses, using both traditional and modern methods, are needed to address these challenges effectively. In recent years, the Western Ghats region of Maharashtra, as well as other parts of India, have experienced numerous landslide events, including two significant occurrences in Raigad District at Taliye happened on July 22, 2021 and Irshalwadi village took place on July 19, 2023. These dates mark significant disasters resulting in substantial loss of life and have prompted ongoing efforts in disaster management and slope stability analysis in the region. Several villages within Raigad are identified as vulnerable to future landslides, prompting district disaster management authorities to compile a list of high-risk areas. This situation underscores the critical need to perform comprehensive slope stability analyses using both conventional analytical methods and contemporary computer-based simulation techniques. In this study, geotechnical engineering data—such as unit weight of soil, cohesion, and internal friction angle—were obtained from existing research literature to evaluate eight distinct slope profiles using established analytical methods, including the Swedish circle method, friction circle method, and Taylor’s Stability Number method. The results were validated against previously published research data. The analysis revealed that slope geometry, particularly slope angle and height, has a more significant influence on stability than the presence of swelling clay minerals. Contributing factors to landslide susceptibility in the Western Ghats include steep terrain, intense monsoonal rainfall, and specific geological conditions; approximately 1.8% of Maharashtra’s land area is classified as highly susceptible. The findings suggest that slope stabilization measures such as excavation at slope crowns, installation of retaining and gabion walls at slope toes
