The high- resolution digital SPOT images and field investigation show that the southeastern segment of Qujiang fault offset the youngest gullies and the I and II grade fluvial terraces． Qujiang fault is a Holocene active right- lateral strike- slip fault，along with some reverse component which offset the Holocene deposit in the trench． The latest activity event is the 7. 8 earthquake in Tonghai in 1970． Investigating typical landform offset by Qujiang fault，at the field of the Wujie and Bailinshan where is the southeastern segment of Qujiang fault，the right- lateral slip rate of this fault is (3. 36 ±0. 1) mm/a and (3. 21 ±0. 3) mm/a，respectively．
