ABSTRACT

ͦ

Many areas are exposed to different types of natural hazards including landslides, which can lead 

to loss of lives, injury to people, damage to property and disruption of economic activities. This 

project assessed the landslide susceptibility and quantifies the hazard and risk related to landslides 

in Okemesi, southwest, Nigeria using remote sensing imageries and geographic information 

system (GIS). The result revealed that slope, elevation, aspect, distance from road can influence 

landslide susceptibility. Current landslide and the most susceptible areas to landslides were within 

the areas with high slopes especially at slope angles of landslide occurred on slopes between 45ᵒ

and 75ᵒ in the upper, steep and narrow ridge with elevation of between 514m and 666m. It was 

further revealed that the landslide occurred about 500 m close to the road and potential areas were 

landslides can occur in the future are closely located within the 0-200 m buffer zones. Generally, 

Slopes have more influence than land cover for the susceptibility map. Although a smaller portion 

of the study area is presently located in the high hazard zone, intensive land use activities on the 

steep slope could expose the land to other triggering factors such as rainfall. A landslide 

susceptibility assessment and monitoring will assist in prediction, management future occurrences 

and general developmental planning in the area.
