Daftar Isi:
  • The potential of landslide in some area in Abang district, Karangasem Regency, Bali, has been identified by using ground penetrating radar and geoelectricity with dipole – dipole configuration. The Research has been conducted in 6 sites. The interpretations of GPR and Geoelectricity revealed the presence of clay (8.52 cm/ns and 11.8 – 18.6  m), saturated sand (12.11 cm/ns and 216  m) and water penetration (3.23 – 4.27 cm/ns and 7.5 – 60  m) at 2 – 5 meter below the subsurface. The slip surface is detected at 5 – 8 m depth. The result of sample laboratory test show high plasticity limit (27.13 – 24.51) and liquid limit (34.50 - 30.00) which leads to landslide phenomenon.
