Abstract

Northern Potwar Deformed Zone (NPDZ) is a part of the foreland zone of NW Himalayan folds and thrust belt. Seismicity map has been prepared for this region, which appears to be less active as compared with adjacent regions with apparently no distinct pattern or relationship with surface structures. Focal mechanism solutions of 4 events, for which required parameters are available, indicate left-lateral strike- slip faulting for 3 events and thrusting for one event. P-axes orientations are in NW-SE and NE-SW. Basement is most likely involved in the ongoing deformation.
