Landslides are present in all continents playing important role in the continual evolution of this type of or similar geohazard. They constitute a serious hazard in many areas of the world. The landslide event can be single or multiple. This paper involves the geotechnical analysis of landslide that occurred in Amuzukwu Abia State Nigeria. Amuzukwu landslide of about volume 3.5 x 104 m2 which was classified as rotational has a detached surface which is roughly circular and spoon-like. The paper also discussed the manifestation, causes and effect of landslide. For geotechnical analysis, samples were collected from the site of the landslide and subjected to the following soil tests: natural moisture content, specific gravity, relative density, Atterberg limits, sieve analysis, compaction, permeability, shear strength, and unit weight. Slopes adjacent to the slides that are still intact were also analyzed using Plaxis 2D to determine their factors of safety. Both the geotechnical laboratory results and Plaxis 2D results reveal that another landslide is inevitable if the conditions of the infinite slope is not improved using the methods recommended in this paper. Some of the methods recommended include cutting back of slope to reduce its gradient, reinforcement (using Reinforced concrete), soil nailing as well as anchors and retaining structures.
