“…The geophysical technique on this study was the electrical resistivity tomography (ERT) method measurement. The resistivity method has been confirmed to be functional for subsurface study related slope prone to landslide [9], [10]. ERT depicted soil moisture; delineate landslide body, shape, slip surfaces and depth; and delineate slope instability [11], [12].…”

This study used geological, geophysical, and geotechnical methods to investigate the causes of landslides in a newly established Cileunyi Sumedang Dawuan (Cisumdawu) Highway, Sumedang Regency, West Java Province. A combination of geological field observation, subsurface geoelectric resistivity-based survey, and borehole drilling were applied to obtain the subsurface data of a research area. A total of 10 boreholes were drilled to collect geoengineering data, including the soil material and N-SPT value for validation purposes. The soil hardness and resistivity were measured and compared to establish the relationship between resistivity and engineering properties. The result revealed that percolating water zone in the permeable loose soil was located above the impermeable layer, estimated as a slip surface. The analysed subsurface measurement and borehole data showed that the depth of the slip surface is between 26-27m. The study is important to determine the mitigation steps for the highway slope stability construction.

The vulnerability of landslides in Lantan Village, North Batukliang District, Central Lombok Regency has been analyzed using geoelectric data, rainfall, soil movement, and topographic slope. Resistivity data was acquired by the G-Sound resistivity meter using the dipole dipole configuration method and visualized using the RockWorks15 software. We also used rainfall data and ground movement data. The ground movement was estimated from Sentinel-1A satellite data, processed using the DInSAR (Differential Interferometry Synthetic Aperture Radar) method. The slope data was obtained based on the topographic slope map of the Central Lombok Regency. The results showed that the slip surface was indicated to be located in silt clay with sand and the direction of the landslide in the study area was to the northwest with the type of landslide that might occur was a type A translational landslide. The depth of the slip surface varies from 1.5 m to 21.5 m. The average monthly rainfall varies from low to high (<100 – 300 mm) with a monsoon rain pattern. Land movement in the form of land subsidence was observed at a rate of -0.27 to -0.30 cm/year during 2018 - 2020, with average land subsidence of -0.285 cm/year. The potential for landslides is also seen from the slope value of 40°, which is categorized as very steep. With all these conditions, the level of vulnerability to landslides in Lantan Village is high, and hopefully, the results of this study can be a reference for related parties in making efforts to minimize the impact of this disaster.

“…Research about landslides using the geoelectrical resistivity method has been carried out by Abidin et al [11] in Malaysia, Bellanova et al [12] and Hojat et al [13] in Italy, and Cebulski et al [14] in Poland. Some of these studies indicate that the geoelectric resistivity method effectively determines subsurface conditions in landslide-prone areas [15].…”

Extreme weather triggers high-intensity rainfall, and it triggers land movement that eventually becomes landslides. The water of rain will enter to the ground through the rock gaps and accumulate along the landslide area to reduce effective stress and reduce the shear strength of the soil. Morphologically, Sukaresmi Village, Cisaat Sub-District, Sukabumi Regency is located at the foot of Mount Gede with a bumpy surface relief. This condition is one factor that triggers landslides because the soil is prone to movement. This research aims to identify the field slope zone for landslide prediction in the Sukaresmi village, hoping that the surrounding community could anticipate further landslides. The research was carried out using the Geoelectrical Resistivity method of the Schlumberger configuration as many as eight measuring points with 1 m electrode spacing. This research indicates that the subsurface conditions are divided into three constituent rocks: Clay, Tuff, and Volcanic Breccia. The field slide zone is located between the Tuff rock and turf layer at a depth of 4-7. 5 m long, 82 m (Line 1), and 40 m (Line 2), with a resistivity value range of 56-158 Ωm. The efforts that the local government can make to anticipate the condition of the building to remain safe include analyzing soil stability, strengthening slopes, and making retaining walls to increase the value of the safety factor.
