Abstract: We have analysized the data of seismicity,geology and crustal deformation geodesy along the Xiaojiang fault zone. It is found that this strike-slip fault is characterized by alternative deformation of compressive uplift and extensional subsidence. Considering its correlation to distribution of historical earthquakes,it is suggested that this feature of fault deformation may be associated with the process of the strain accumulation of the Xiaojiang fault zone. This is of great importance for the analyses of seismic risk in this area and determination of potential source area of future major earthquakes.
