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.
