Geomorphic features along the active faults in the Lohit and Dibang Valleys, Eastern Arunachal Pradesh, India

Description :
Field studies coupled with interpretation of topographic maps resulted in the identification and delineation of a large number of trending active faults which post-date the NW-SE oriented thrust system and shear zones. Recent movement on the northerly-trending faults has caused not only pronounced deflection of rivers and streams but also damage to recently constructed river bridges and subsidence of roads. Movements along faults and thrusts are also responsible for the abrupt rise of mountain front, occurrence of a planar scarp and triangular facets devoid of gullies or with a few straight furrows, huge landslides, abrupt narrowing down of wide meandering rivers, uplifted fluvial terraces and blockage of streams.
