The assessment and mapping of seismic landslide hazards： A case study of Yingxiu area, Sichuan Province

Abstract：Although there exists controversy concerning the problem whether the Earth has entered into the earthquake-prone period or not, it is generally accepted that the frequency of the recent devastating earthquake is higher than that in the past. The earthquake-induced landslides are increasingly becoming the research focus of geologists. The prediction of the earthquake-induced landslide prone area and the assessment of the seismic landslide hazards are of great significance for reducing casualties and property losses after a regional long-term earthquake prediction. In this paper, the commonly used seismic landslide hazard evaluation methods are presented and the advantages and disadvantages of these methods are discussed. As an example, the seismic landslide hazards assessment and mapping in Yingxiu area was conducted by using Newmark model.
