Landslide Killing Himalayas: Collective Study on Causal Factors and Possible Remedies

Abstract

Soil is naturally available material used for construction all over the world. When this material available in form of natural slope can cause landslide. Purpose of this study is to understand behavior of different causal factor of landslide at Himachal Pradesh and then suggest some remedial measure. To fulfill this, aim five-year data of precipitation for every district is collected from metrological department and analyzed. Data of earthquake activities is also collected. Work done by different author in this area is analyzed thoroughly. It is found that the change in climatic conditions such as increase in precipitation over years, earthquakes and anthropogenic interference has increased the landslide susceptibility of area. Remedial measure suggested as use of landslide susceptibility zonation map future land use pattern, use of advance technology like soil nail and gabion wall and use of numerical modeling to analyze slope stability.
