The active fault zones and their nearby areas are liable to encounter the serious Slow-Moving Slop Disasters (SMSD), and small surface deformation is one of the important signs to recognize the SMSD. With the active Xianshuihe Fault (XSF) zone in the eastern Tibet Plateau as an objective, this study obtained the millimetric deformation through collecting multiperiod ALOS/PALSAR data for time series InSAR process, along with field investigation, remote sensing interpretation and geological setting analysis. The results reveal types, deformation features and spatial distribution of the SMSDs. ① Along the active fault are developed three kinds of slope geohazards: creep landslides, debris flows and slowmoving moraines. ② Creep landsides have the geomorphic characteristics of garbled contour steps, which present rough, uneven longitudinal profiles, toughshaped landscape, and no exposed batholiths, etc. ③ Paleolandslides, coseismic landslides and shattering slopes are well developed within the Xianshuihe fault. Those geohazards directly intersected with the Xianshuihe fault show slowmoving deformation while those geohazards without crossing the the Xianshuihe fault show no slowmoving deformation, reflecting that active faulting has controlling role in geohazard development. ④ Two types of debris flows, “Soilstone Forest” and “Loose Debris Slope”, were found to occur in this area. The slow, disperse deformation in source areas and the amount and velocity of deformation are the important identification features. ⑤ In the areas (above 4200 m a.s.l.) nearby the Xianshuihe fault are widely distributed slope deformation of modern moraines along glacial troughs, which is characterized by huge single body and fast moving velocity and should be the main manifestation of denudation in the study area. The study results also show that combination of InSAR technology with geological settings can effectively identify SMSDs, and is suitable for geohazard investigation in the environment of mountainous areas with great amount of disasters. Therefore, it will be an important direction in geohazard investigation technology.
