Linear features registered on the Landsat imagery and seismic activity in the Dharamsala-Palampur region (NW Himalaya)

Abstract

The Dharamsala-Palampur region of Kangra district (Himachal Pradsh, NW Himalaya) has been studied to infer the stress filed pattern and tectonic movements responsible for the generation of high seismicity in the region. The referred area reveals large number of lineaments, generally a manifestation of various structural features like folds, faults, fractures, etc. The different types of lineaments were differentiated through a lineament filter map. The rose diagram and linear histogram of lineaments are drawn to reveal major trend of linears and their correlation with the seismicity of the region. The major thrust systems are cut and offset by the transverse lineaments which have direct relationship with the complex tectonic history of this region.
