Many inactive fault lineaments developed in Kulon Progo Mountains, which are mainly composed of Oligo-Miocene age (33,9 - 5,3 million years ago) of volcanic rocks. The directions and distributions of the lineaments differ from one part to another. This research was conducted to reveal the fault lineaments on controlling disaster variation of the area. Fault lineaments delineation is done on the area of all Kulon Progo Mountains. Fault lineaments density variation map is made from the fault lineaments. Fault lineaments density variation map that overlaid by slope map will show the result in a relationship between the fault lineaments density and the potential disaster of the area. The result of fault lineaments density analysis shows that high-density values area tend to be landslide and rock slide at the volcanic rocks. High fault lineaments density with relatively low slope percentage has subsidence potential at limestone area in the central part of Kulon Progo mountains. The disaster tends to happen especially in the area of old rock formation with high fault lineaments density.
