The present study investigates the factors associated with the occurrence of landslides along with the National Highway (NH 39) connecting Assam-Manipur (India) to Myanmar. Kinematics and slope stability analyses were used to gain an understanding of the causes of slope failure despite the terrain comprising material with a high safety factor. The study area falls within a high seismic zone along the regional Churachandpur-Mao Thrust (CMT) situated west of the Indo-Myanmar subduction zone. Based on these studies of seismicity, slip rates, creeping, among others, it was inferred that CMT is a creeping regional fault running parallel to the subduction zone boundary creeping segment of CMT and that the CMT requires further monitoring to assess the landslide hazard in the region.
