Both laboratory and field work have been done. The investigation was done on five mass movement slope locations: Keunom Tiben, Ogwei Tiben, Ofen Tiben, Numba, and Fifty One. Each slope's safety parameters were determined. The materials under study have a water content ranging from 15.1 to 47.4%, are porous (44–58%), and are not extremely plastic with plastic (14.8–29.3%). They are hence extremely vulnerable to creep. Furthermore, the comparatively weak friction angle spans from 5.68 to 32.13°, while the cohesiveness is quite low, ranging from 0.10 to 0.45 bars. Additionally, the Ogwei Tiben, Ofen Tiben, Numba, and Fifty One sites had safety factors of 0.85, 0.98, 0.99, and 0.65 less than 1, respectively. Keunom Tiben is stable, nevertheless (FOS = 2.96). These slopes are hazardous to the nearby population and structures because the safety factor tends to zero as the water height in each profile increases. Widikum. Mass movement. Safety factor.
