To find out and observe landslide hazard, it is necessary to identify and mapping the area. This study was conducted from November 2017 to April 2018 at nine villages in Ngargoyoso sub-district. The method of the study was scoring of rainfall, slope, land use, geology, permeability, texture and effective depth of soil. The landslide-prone area were classified into three classes, i.e., low, medium, and high of landslide-prone. Low landslide-prone class had characteristics of flat slope with land uses are in the form of settlement, plantation, rice field and moor. The dominant areas are located in the land mapping units of 1,3,4,5 and 9 in Dukuh, Nglegok and Puntukrejo Villages. Medium landslide-prone class had characteristics of steep to very steep slope with land uses are in the form of forest/plantation, settlement, shrubs and rice field. The dominant areas are the in the land mapping units of 3, 4, ...
