Loess landslide induced by earthquake is a serious secondary disaster in Xiji County of Ningxia Hui Autonomous Region. It has special characters not only in scale but also in density

the major type of which is characterized by low angle

high speed and far distance.Xiji County is in a more active period of seismic ac-tivity at present and old landslides may easily revive in the case of continuous rain and heavy rain or earth-quake

with a serious threat to people's lives and property and severe influences to local economic construc-tion. Based on detailed field data from geological disasters surveys in the county

a classified statistic of seis-mic loess landslides are made by size

formation age

thickness of sliding mass and other aspects.Then the boundary characteristic

surface and inner characteristic

deformation characteristic and sliding characteristic of the landslides are analyzed.Furthermore

the spatiotemporal distribution of the landslides are summa-rized. The research may provide a theoretical basis for the forming mechanisms of the landslides.
