Abstract The Qaleh-Sorkh Fault with N-S trend, 57 km length and right-lateral strike-slip Mechanism is one of the seismic and active faults in north of Sistan suture zone. Combining data obtained from satellite imagery, geological maps, shaded rather elevation model and field observations use for morphotectonic investigations in this fault, which shows quaternary sediments cut, bend or move the direction of streams with right-lateral component. Until now has been reported numerous disasters historical and instrumental earthquake in east of Iran. So, morphotectonic and paleoseismology studies have been important role in the provider of the seismotectonic models. According to this, determination of seismic parameter and seismic action in the Qaleh-Sorkh fault needed to do paleoseismologic investigation. So, this fault site locate selected

-Abad site. In this location excavated one main trenching with 21 m length, 4.5 m depth and N80°E trends and two secondary trenching for more evidence. Preliminary results on main trench of Qaleh-Sorkh fault in Jannat-Abad site show at N7°W, 72°E in this faults that have a right-lateral slip with thrusting component. Keywords: east of Iran, paleoseismology, morphotectonic, Qaleh-Sorkh fault, active fault.
