Abstract
Karangsambung regions is located in Kebumen District of Central Java Province which morphologically is composed of sloping montains and hills, therefore Karangsambung region has landslide hazard potentials.Ground Penetrating Radar (GPR) methods has conducted in these research to delineating slip plane of landslides potential areas as the base of landslide potential assesments. GPR measurements consists of four lines which has a length of 170 - 550 meters than the field data has processed to produce the radargram section. The radargram section has interpreted to delineating slip plane of landslides, and as the results slip plane has detected in the depth between 5 - 20 meters from surface and has potential of landslides occur.
