Abstract: Landslides are one of the most prevalent catastrophes in the world, which can be caused by a variety of factors, human-related and natural. This study looks at the landslides that severely damaged Taliye village in the Raigad area of Maharashtra State, and it investigates the relationship between the causes of landslides and the primary contributory factor. Out of all the techniques for researching, detecting, and mitigating landslides, remote sensing and GIS have the best precision and dependability. Significant pre- and post-disaster changes in slope, land use, contour, hill shade, soil texture, NDVI, and rainfall were found through a comparative study of digitally processed thematic layers, highlighting the region's susceptibility to landslides. In this instance, we utilized the rainfall data and Weighted Overlay Method to analyze causative elements effectively. Efforts are made to identify the landslide key indicators in pre-landslide results and causative factors behind devastating landslides through post-landslide results. A major observation of the pre-and post- landslide susceptibility map classifies the area into six categories, with high-risk zones 5 and 6 showing 1.13 and 3.93%, respectively, reduced to 0 and 0.07%. It is obvious that the collapse of the zone vulnerable to landslides is what caused this alteration. Meteorological data, such as rainfall stats, serve as evidence to show that a significant amount of input led to triggering landslides. Therefore, it is crucial to apply these findings more broadly in order to formulate preventive strategies that are intended to mitigate potential repercussions and safeguard the welfare of every individual concerned.

INTRODUCTION Landslides, characterized by the downslope movement of soil, rocks, debris, and mud, are natural phenomena that often lead to significant destruction of human life, infrastructure, and topography. These events are common worldwide, particularly in mountainous regions where steep and curved slopes act as catalysts, causing substantial injuries, fatalities, and property damage (Parise and Jibson 2000; Dai et al. 2002; Glade et al. 2005; Kanungo et al. 2006; Pan et al. 2008; Girma et al. 2015). Landslides can be triggered by various factors, including heavy and prolonged rainfall, earthquakes, rapid snowmelt, and human activities. Their movements can involve flowing, sliding, toppling, or falling, often displaying a combination of these types (Crozier 1986; Cruden and Varnes 1996; Dikau et al. 1996). Deccan Plateau's Western Ghats are already well-known for being a region of mountains and valleys. Mesas, buttes, and escarpments are among the geomorphological features that characterize the Western Ghats. This coastal section of Maharashtra state experiences the most rainfall during the monsoon season. Perhaps for the previously described reasons, the Western Ghats are prone to landslides.
