Instrumental Monitoring of Mansa Devi Landslide Site and Interpretation of Data

摘要

Landslide has the second rank in the amount of damages due to Natural Hazards. It represents one of the natural hazards with most costly catastrophic events in terms of human lives and infrastructure damage in the world, even if often damages caused by mass movements are addressed to other natural phenomenon such as floods or earthquakes which are their main triggering factors. In hilly regions, landslides constitute one of the major hazards that cause losses to lives and property. A slope failure is developed due to progressive external loads and deteriorations of slope geo-materials. This progressive and dynamic development results in occurrence of landslides. During the last decade, it has been observed that phenomenon of localized severe rain and human intervention such as land development has greatly increased the risk of landslide. Landslide cause damages to infrastructure such as roads and railways and the resulting disruption to transport networks makes a major impact on local communities and finally economies. Therefore to minimize the damage caused by landslide is of paramount importance.
