| Summary: | This study aims to identify and analyse potential landslide slip zones in the landslide-prone region of Bandung, specifically in Cikahuripan Village, Lembang, West Bandung, West Java, Indonesia. The novelty of this research lies in the integration of Ground Penetrating Radar (GPR) and 2D Electrical Resistivity Tomography (2D ERT) measurements to provide a comprehensive understanding of subsurface conditions. GPR, using a 100 MHz shielded antenna, and 2D ERT, employing a dipole–dipole configuration, were conducted along six profiles to generate a quasi-3D resistivity cross-section. This approach identified three distinct lithology layers – sandy tuff, clay tuff, and lava breccia – with resistivity values ranging from 19.5 to 74 Ωm, 5 to 19.5 Ωm, and more than 74 Ωm, respectively. The integration of geophysical data revealed a potential slip zone within the clay layer at a depth of 4–16 metres. The consistency and mutual reinforcement of the GPR and 2D ERT results underscore the reliability of the findings, offering new insights for effective landslide mitigation strategies in the region. |
