| Abstract | : | A Geophysical survey using resistivity method with Schlumberger and Dipoledipole configuration had been used to determine subsurface landslide area at Penggung Purwosari Village area of Girimulyo, Kulonprogo Yogyakarta in Indonesia. This study aims to determine the structure of the subsurface layer using 1D and 2D resistivity methods, as well as to know the characteristics of slip-surface and type of ground movement that would occur. The result of resistivity data processing shows that the variation of subsurface resistivity value consists of three layers. The first layer is characterized by a resistivity value of <9?m interpreted as soil saturated with water in the form of surface soil, the second layer is characterized by a resistivity value of 9-36?m is interpreted as a water-unsaturated soil layer, and the third layer is characterized by a resistivity value of 36-70?m interpreted as a base layer (bedrock) of andesitic-breccia. The soil and weathering layer can be accumulated above a curved bedrock interpreted as a layer that has a possibility to create slippage plane and produced a rotational slide and has the volume about 790,612m3 . Areas with high landslide vulnerability could be at north and north-west of the study area. |
