The second Songhua River fault is a long NW-trending fault in Northeast China. The fault is running through the whole province of Jilin and found to be consisted of four separate segments. This study focuses on one of the four segments, the Fengman fault segment. Through the satellite image interpretation, field geological survey and the application of geological radar detection technology, the authors suggest that the Fengman fault segment is made up of three parallel branches, and dips northeastward or southwest at high angles. Evidences from the geological surveying and the dating of fault-gouge also suggest that the latest activity of the Fengman segment of the fault occurred in the middle Pleistocene.
