Ascertaining the Neotectonic Activities in the Southern Part of Shillong Plateau through Geomorphic Parameters and Remote Sensing Data

Study of quantitative morphometric parameters was taken up in four major river valleys in the southern part of Shillong Plateau using SRTM DEM in GIS. The study indicates that the region is undergoing differential uplift. This is evidenced by preferential tilting towards east, while the central part of the plateau exhibits higher rate of uplift than the eastern and western segments. We ascribed the higher rate of uplift in the central segment of Shillong Plateau to the activity along the Dapsi Thrust and Dauki Fault.
