Hazardous potential analysis from landslide slip plane delineation based on ground penetrating radar (GPR) methods in Karangsambung, Kebumen, of Central Java

Abstract

Karangsambung locations is in Kebumen District of Central Java Province which morphologically is composed of sloping mountains and hills. Therefore, Karangsambung region has landslide hazard potentials.Ground Penetrating Radar (GPR) methods have conducted in this research to delineating slip plane of landslides potential areas as the base of landslide potential assessments. GPR measurements consist of four lines, which have 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 depth between 5 - 20 meters from surface and has the potential of landslides occur.
