Recent Trends and Techniques in Landslide Hazard Assessment

Abstract

Landslides are a serious concern in steep terrain where severe storms are common. The magnitude of landslide risk depends not only on storms and the physical characteristics of the land, but human activities, especially agricultural practices, are important. An essential stage in the management of landslide risk and hazard is landslide hazard assessment. Landslide Hazard Zone (LHZ) choice processes include intuitive, half size, Quantification, Probability and Multi-criteria approaches. Among the various techniques used traditionally, Multivariate approaches, albeit with limitations, to assess landslide risk at a regional scale Very feasible and cost effective. Over the past two decades, landslide research has expanded use of the sophisticated tools of remote sensing and geographic information systems (GIS) to study landslide hazards.
