Continuous convergence of the Indian and Eurasian plates along the Himalayan arc is manifested as uplifted topography, short and long term shortening rates and inter-seismic strain. The proportion in which each of the above said elements contributes is, however, different along different sectors of the Himalaya. For example, the bulk shortening along the central part of the Himalaya is mainly accommodated along the Himalayan Frontal Thrust (HFT) (Wesnousky et al., 1999; Lave and Avouac, 2000). Accordingly, it has been hypothesized that the tectonic wedge of the Sub-Himalaya represents an expanding mountain front, in the central part. The present study is aimed at testing this hypothesis in the NW Himalaya of India by integrating field observations and results of geomorphic investigations.
