Abstract
Initiation of potential hazard mapping of landslide movement in northern Sumatera becomes the main priority in disaster mitigation. Mitigation of landslide is expected to decrease and avoid the impact of landslide movement disaster. Concrete steps to anticipate improper land usage can be done by mapping its potential hazard. Disasters may arise as a result of human activities (anthropogenic) and natural factors. Approachment to the triggering factors is done by overlaying and scoring the parameters that trigger the landslides movement. Based on its statistical approach, we can conclude that North Sumatra province has the potential of landslide movement. The lowest potential of landslide movement is 5,94 % ; lower potential 74,23 % ; middle potential 19,52 % and the highest potential is 0,03% from the total area ofthe province of North Sumatra
