The road network in the Himalayan terrain is vital for India's socio-economic development and national security, yet complexities of topography, geological structures, diverse lithology, neotectonics make planning maintaining these routes a challenging task. Population growth expanding construction have caused slope destabilization, mass wasting, movement across terrain. Field-based stability assessments are essential characterization stabilization, helping planners predict select suitable strategies roads other infrastructure. This study presents comprehensive displacement analysis Kuther landslide, situated along Jawali to Dehar Watershed, Kangra District, Himachal Pradesh. An integrated approach was used, combining surface monitoring with COSI-Corr technique through methods such as rock rating, kinematic analysis, continuous rating. Findings indicate that highly susceptible planar failure, some instances wedge failure. ranges from class III IV, indicating conditions partially stable stable, while reveals creeping at an average rate 4 mm/year. highlights critical need analyses ensure safety vulnerable areas their communities.
