The purpose of writing this article is to analyze landslide hazards, landslide morphometry and predict the number of populations loss who have the potential to be affected by landslides. The method used is in the form the survey method is used to determine the landslide morphometry and literature studies are used in the form of population data. The results showed that the natural disaster hazards of landslides can be divided into three parts, i.e; low, medium and high natural hazards. The low natural hazard of landslides is generally found in the plains region in the form of alluvial plains and coastal alluvial plains. The hazards of a moderate landslide are generally found in low hilly areas and hilly, while the natural disaster hazard of high landslides is generally found in hilly areas and volcanic mountains that have undergone a weathering process. Landslide morphometry found in the study area was in the form of rotational and translational type landslides. Rotational landslides are natural disasters of landslides that have a sloping plane in the form of a basin and the type of translational landslide has a sloping plane parallel to the direction of the slope. The results of the prediction of the population loss that will be affected by the biggest natural disasters are village Siguntur, which is 3006 people, Kampung Baru Korong Nan Ampek, 1887 people and village Barung-Barung Balantai which is 1775 population. © Int.
