The paucity of landslide events dataset has however been a major limitation to constructing landslide models for performing meaningful task. Hence, the study developed a Geographical Information System (GIS) database and mapped landslides and associated events in Nigeria, West Africa. The study was carried out by scientists from Centre for Geodesy and Geodynamics, Toro, Nigeria during three field seasons which includes desk study, compilation of existing data and publications, meetings and discussions with governmental organizations at Federal and State level, focus group discussions with elders and local residents, and visits to landslide and associated events sites. The study provides summaries of the countrys geology, topography, geomorphology, hydrography, climate, vegetation and soils, and shows how different geoenvironmental factors influence the occurrence and frequency of Landslides and Associated Event in Nigeria.
