Research has been carried out on the existence of slip surfaces in Wanurejo, Borobudur District, Magelang Regency, Central Java. The location of the slip surface is identified using the resistivity method of the dipole-dipole configuration. This research was conducted at a relatively flat measurement location and at an altitude of around 95–105 meters above sea level. Measurements were made on 6 different lines with a length of track 1 of 250 m. The results of data processing indicate that the layer that acts as a slip surface is a layer of clay. The clay layer has a resistivity value ranging from 15 to 35 ohm.m, which is relatively thin, so it has the potential to become a slip surface because it is located between two rocks that have a significant resistivity contrast: compact andesite rock and water-saturated sandstone. If the water-saturated sandstone layer is no longer able to withstand the weight above it, the surrounding andesite rocks will easily slip. This is also reinforced by the presence of a layer of clay that is slippery, so the potential for landslides or slipping is greater.

“…The thickness of the landslide material is the distance from the earth's surface to the slip surface. The depth of the slip plane has been widely studied by experts, generally using geoelectric methods such as those carried out by Yatini et al (2018) and Suardi et al, (2019). Another researcher, Xie et al (2020), used a method based on the slope of the earth's surface; VES and HVRS methods by Pandavenes et al (2023).…”

Analysis of landslide slip surface based on the engineering properties of tuff rocks, including shear strength, water content, and infiltration rate on the West Sinjai road section, South Sulawesi, Indonesia. This study aimed to analyze the effect of shear strength, water content infiltration rate, and weathering grade of tufa rocks in the study area. The methods used in this study area included a study of weathered tuff profile characteristics, weathered tuff infiltration testing and residual soil (RS) determination of weathered tuff water content and residual soil, and testing of shear strength of weathered tuff and residual soil. This research used aspects of engineering geology, including shear strength, water content, and infiltration rate, as well as rock weathering grade to determine the slip surface in tuff to determine the volume of landslide material. The results showed that the tuff profile consisted of four grades, namely moderately weathered tuff (MW), highly weathered tuff (HW), completely weathered tuff (CW), and soil residual (RS). The rate of tuff infiltration increases with increasing weathering grade. The water content is more significant with the high degree of weathering of tuff. At the same time, the shear strength decreases with high weathering. Therefore, the research area is prone to landslide events. The slip surface is in a layer of moderately weathered tuff rock (MW), and those that experience landslides are highly weathered tuff rock (HW), completely weathered (CW), and residual soil (RS).

“…This method utilizes electromagnetic waves, is non-destructive and has a high resolution of the dielectric contrast of the earth material and is capable of detecting subsurface vertical profiles with high resolution depending on the frequency used [5]. The research [6] and [7] which was conducted using the geoelectric method, was able to determine the structure of the subsurface rock, identify the potential slip plane for landslides and the slope, based on the resistivity value. The results of the second study show the thickness of the unstable layer and the shape of the slip plane of potential landslides obtained from the distribution of rock resistivity values.…”

The application of the Ground Penetrating Radar (GPR) method which was carried out in the Prambanan District, Sleman, Special Region of Yogyakarta was to determine the geometry of the slip plane of potential landslides. This method can see the contrast between the slip plane of the landslide and the landslide material that is above the slip plane. Measurements were made on field "A" consisting of 6 tracks and field "B" consisting of 7 tracks. The cross section of the radargram shows a penetration depth of about 6 - 7 meters, divided into 3 layers, namely, the S1 layer (soil), the S2 layer (transition zone), and bedrock. The depth of the slip field for potential landslides produced at the boundary layers of S1 and S2 is about 1 – 1.5 meters and the depth of the boundary layers for s2 and bedrock is about 2 – 3 meters. The geometry distribution map of the slip plane shows the type of landslide in the form of a translational landslide.
