Based on geomorphologic analysis by the high-resolution satellite (American Landsat ETM), combined with field observation and measurement on the tectono-geomorphologic characteristics in the studied area, activity of the Yuanmou-Xigeda Fault during the Late Quaternary was studied. The morphology of the rivers and ridges along the fault shows "S" type with en echelon arrangement. Meanwhile, the fault activity indicates sinistral strike slip and formed a number of pull-apart basins and rift lakes along the fault belt. Since the Late Quaternary, the current tectono-geomorphic features in the studied areas were formed by the activity of the Yuanmou-Xigeda fault which shows sinistral strike slip strongly and local inclined slip. The mid-southern section of the fault suffered the maximum horizontal principal compression stress of the NW-SE strike and the northern section of that was affected by the maximum horizontal principal compression stress of the NNW-SSE strike
