Abstract: Since having historical records, there have been many times middle or small earthquakes occurred along the Susong-Zongyang fault, southwest area of Anhui province. This paper gives a synthetic study on the fault by means of macro-microscopic structural analysis, dating of the deformational materials, and combing with a series of seismic safety evaluation of the enginnering sites in this area. Based on the aforementined work, the authors revealed the geological background of middle or small earthquakes along the fault, and forecased initially the level of seismic acitvity nearby the fault in future. It offers an example to evaluating fault's active behaviour in the areas of lower seismicity.
