Abstract
Landslides produce an awesome picture of the hill sides with steep scarred, hollowed and gullied geomorphic features devoid of vegetation particularly between the major thrust zones. A look on the tectono-stratigraphic map of the region with marked major tectonic features like the Main Central Thrust (MCT), North Almora Thrust (NAT) and South Almora Thrust (SAT) indicates that the region is highly prone to landslides and is affected by repeated tectonic and orogenic processes. These factors with the nature of the rocks, climate and the heavy monsoon rains are responsible for sculpturing the region. The mountain features and the valley slopes thus indicate the influence of the activities and the dynamic forces at a particular locality and time. Many times developmental activities have also contributed towards the degradation of the environs due to disturbance of the already stabilized slopes and the angles of repose e.g. along the Rishikesh-Badrinath Road, where a new alignment has been given, sometimes overlapping the old pilgrim route.

Lithotectonic Landslides and Hazards in Parts of Garhwal-Kumaon Himalayas
Landslides produce an awesome picture of the hill sides with steep scarred, hollowed and gullied geomorphic features devoid of vegetation particularly between the major thrust zones. A look on the tectono-stratigraphic map of the region with marked major tectonic features like the Main Central Thrust (MCT), North Almora Thrust (NAT) and South Almora Thrust (SAT) indicates that the region is highly prone to landslides and is affected by repeated tectonic and orogenic processes. These factors with the nature of the rocks, climate and the heavy monsoon rains are responsible for sculpturing the region. The mountain features and the valley slopes thus indicate the influence of the activities and the dynamic forces at a particular locality and time. Many times developmental activities have also contributed towards the degradation of the environs due to disturbance of the already stabilized slopes and the angles of repose e.g. along the Rishikesh-Badrinath Road, where a new alignment has been given, sometimes overlapping the old pilgrim route.
