“…We also compare qualitatively the results obtained from refraction seismic and electrical resistivity campaigns, adding the closest lithological log data in ERT 2-SRT 2 crosssections, and showing a good fit among them (Figure 6). The values of both seismic P-wave velocity and electrical resistivity that we assigned to limestones and siltstones are analogous to the values reported by the authors of [50,51] A second layer is defined by higher velocities (2500 m/s < Vp < 3000 m/s), and it is placed below this first layer. The thickness of this layer is also variable with an average of 6 m (SRT 1 and SRT 4) up to more than 10 m (SRT 2).…”

Geophysical surveys are a noninvasive reliable tool to improve geological models without requiring extensive in situ borehole campaigns. The usage of seismic refraction tomography (SRT), electrical resistivity tomography (ERT) and borehole data for calibrating is very appropriate to define landslide body geometries; however, it is still only used occasionally. We present here the case of a Spanish Pyrenees slow-moving landslide, where ERT, SRT and lithological log data were integrated to obtain a geological three-dimensional model. The high contrasts of P-wave velocity and electrical resistivity values of the upper materials (colluvial debris and clayey siltstone) provided accurate information on the geometry of the materials involved in the landslide body, as well as the sliding surface. Geophysical prospecting allowed us to identify the critical sliding surface over a large area and at a reduced cost and, therefore, gives the geophysical method an advantage over borehole data. The three-dimensional model was used to carry out stability analyses of a landslide in 2D and 3D, which, coherently with previous studies, reveal that the lower part is more unstable than the upper units.

Subsurface rock identification in infrastructure construction is important to get the information in planning and monitoring the rock carrying capacity and groundwater systems for infrastructure construction. To get the subsurface condition information that are relatively shallow with detailed results, Resistivity method with Wenner configuration is used. Research is in Benowo area, where dominated by pond area. This research used 5 Resistivity lines, which are divided into 2 locations separated by distance of about 2400 meters as Z1 and Z2 areas. For the subsurface resistivity section at Z1 area there are 2 lines, while at Z2 area there are 3 lines. It is known at Z1 area, top layer is topsoil (2.26-33.00 Ωm) and the bottom layer was identified as clay (0.30-2.26 Ωm). At Z2, top layer being topsoil (0.306-0.708 Ωm), followed by clay layer (0.100-0.306 Ωm), and the sand layer (0.231-0.535 Ωm) in the bottom of resistivity model. Groundwater system shows topsoil acts as a vadose zone, clay layer acts as an aquiclude and the sand layer acts as an unconfined aquifer. Saturated water influences the low resistivity value measurement related to the environmental condition dominated by pond area, beside measurements in rainy season are also suspected to be the cause of low resistivity measured. To be applied infrastructure development in the Benowo area need further treatment activity like soil and/or rock pavement to support infrastructure safety. This research result is related to geotechnical aspects like rock coring, pavement, and optimum architectural design can be an alternative for further research.
