The development of landslides has been ascribed essentially to exogenic and endogenic causes. Thrusts and faults have traditionally been considered as one of the major causes for the control on the distribution of landslides in the Himalayan region. This study describes and explains the relationship between the spatial distribution of landslides and the Main Central Thrust (MCT) in the Satluj (Sutlej) valley located in the northwestern Higher Himalaya. Seventy six naturally occurring landslides in the area have been statistically analyzed. Hypotheses were formulated on the distribution of landslides around the thrust. Chi-square analyses revealed that the Main Central Thrust (MCT) does not control the distribution of landslides away from the thrust, however, it only influences the spatial coverage of landslides along its strike length.
