Landslide Hazard Analysis and Zonation in Shimla City: A Geospatial Approach
Abstract: The Himalayan region, with its complex geological and topographical features, is highly susceptible to landslides, and Shimla City, nestled in the foothills of the Himalayas, is no exception. This research paper explores the critical issue of landslide hazards in Shimla City using a geospatial approach, with a focus on susceptibility analysis and zonation. Our study involves the collection and analysis of a comprehensive dataset, including geological, meteorological, and topographical information. Geospatial tools and technologies were employed to assess landslide susceptibility, combining factors such as soil type, slope angle, land use, and historical landslide occurrence. Through this analysis, we have identified and categorized areas in Shimla City into high, moderate, and low - risk zones, enabling the development of a detailed landslide hazard zonation map. Key findings of this research paper include the identification of specific regions within Shimla City that are at the highest risk of landslides. We have also determined the influence of geological features and meteorological conditions on landslide occurrences. Moreover, case studies of past landslides in Shimla City provide valuable insights into the real - world implications of these hazards. This study underscores the urgency of proactive landslide risk management in Shimla, especially as urbanization and infrastructure development continue to encroach upon vulnerable areas. Our findings contribute to the growing body of knowledge on landslide hazards in hilly terrains and provide a foundation for informed urban planning, disaster preparedness, and mitigation efforts. By implementing the recommendations derived from this research, authorities and stakeholders can work towards a safer and more sustainable future for Shimla City and other regions facing similar challenges. The output reveals that the entire Shimla falls under four categories of vulnerability ranging from very low vulnerability to high vulnerability.62.02% of the Shimla is prone to low hazard followed by very low at 26.10%, moderate at 11.55%, and high covering only 0.32%. Most of the major settlements are located along moderately vulnerable area.
