The study area falls in the mesoseismal zone of 1905 Kangra earthquake (Mw 7.8). To identify appropriate trenching site for paleoseismic investigation and to understand the faulting geometry, ground-penetrating radar (GPR) survey was conducted across a Hajipur Fault (HF2) scarp, a branching out fault of Himalayan Frontal Thrust (HFT) in a foot hill zone of NW Himalaya. Several 2D and 3D profiles were collected using 200 MHz antenna with SIR 3000 unit. A 2D GPR profile collected across the HF2 scarp revealed prominent hyperbolas and discontinuous-warped reflections, suggesting a metal pipe and a zone of deformation along a low-angle thrust fault, respectively. The 3D profile revealed remarkable variation in dip of the fault plane and pattern of deformation along the strike of the fault.

(2) During the first level of occupancy, EA1 was probably a residential complex (having enclosed walls), and EA2 might be the trading complex (with partially enclosed walls lying opposite to G1). Both the areas were affected during the disaster, and the second level of occupancy EA1 was rebuilt and occupied, whereas EA2 was used without renovation. Moreover, the 1819 earthquake probably destroyed both the areas completely and led to their abandonment.
