In the present work, an attempt has been made to study in detail the seismicity of the Surghar, Marwat, Khisor, Pezu and Manzai Ranges, which are known as the western extension of the Salt Range. For this purpose all available earthquake data with magnitude ≥ 3.0 mb from both international seismological networks as well as the local seismic observatories has been collected and seismicity map of the area has been 

prepared for the period of 1904-2002. Based upon this seismicity map, the study area appears to be more active as compared to the adjacent regions of the Bannu Basin and the Punjab plains. The seismicity is mostly concentrated along the Surghar Thrust, Pezu Fault and the Kurram Thrust. A total of nine focal mechanism solutions of seismic events have been determined. Out of these nine, four are reverse/thrust; three are strike 

slip while two are normal, which confirms the dominance of reverse/thrusting over the strike slip from this part of the NW Himalayan Fold-and-Thrust Belt, Pakistan.
