Georadar and geoelectricity method to identify the determine zone of sliding landslide

[摘要] The aim of this research is to determine the contrast between the sliding plane by observing the parameters of rock types, fractures, and faults that could potentially land slides in Bandar Baru, Lampung Barat, Indonesia by both methods of georadar and geoelectricity. This research uses radar reflection profiling configuration for georadar and dipole-dipole configuration for geoelectricity. For georadar data processing has been done with Reflexwave software and for geoelectricity, data processing has been done with Earthimager 2DINV software to interpret subsurface section. Results of research by both methods of georadar and geoelectricity shows the area of contact between the sand stone with resistivity value of 200-1449 Ωm and clay stone with a resistivity value of 32-100 Ωm at the limit depth of 9 m as a potential zone of sliding landslides where the physical properties of clay stone easily derail massive material on it.
