Abstract

Landslides are common along western slopes of Sahyadri ranges and isolated hills of coastal plains in Konkan region of Maharashtra. Numerous landslides with low magnitude is an important characteristic of slope failures in this region. Though the magnitude of landslides in this region is low, they result in huge losses in terms of property damage and even loss of lives especially those occur along major communication routes. Present paper deals with the spatial distribution of landslides in Raigad district, Maharashtra based on the historical landslide records and field investigations. The landslide occurrence and its relationship with the rainfall has been assessed to determine the role of rainfall, lithology and geomorphology in slope failures. The results of the study revealed that the concentration of landslides in Raigad district is observed in the south and south-eastern hilly tracts of the district. It is observed that the landslide process in this study area is also influenced by geo-environmental factors such as slope, aspect, structure, drainage, roads etc.
