“…Seismic methods have been extensively investigated by academic researchers in various countries, including the use of seismic refraction tomography (SRT) for the determination of stratigraphic thickness variations in landslides [41,43,45,47,48,51,52,58], seismic scatter imaging (SSI) to characterize the interior of landslides [47,58], horizontal-to-vertical spectral ratio (HVSR), and multichannel analysis of surface waves (MASW) to analyze the spatial distribution of subsurface structures [43,49,50]. In addition, the use of ERT for the determination of water content distribution within the landslide and the geometry of the landslide surface [43][44][45][46][47][48][49][50]52,58] and ground penetrating radar (GPR) for the analysis of the spatial stratigraphy of the landslide [3,31,44] are commonly used in electrical methods. To provide a thorough understanding of the complexity of the subsurface, these methods are often calibrated using borehole data.…”

“…This approach allows the investigation of fracture systems in loess landslides, reconstruction of landslide topography and geometry, study of fracture-water interactions, analysis of complex subsurface geological conditions, mapping of landslide surfaces and failure surfaces, assessment of changes in landslide thickness, and identification of paleochannels, landslides, and failures [8,9]. It also assists in the confirmation of changes in the internal structure of landslides, the identification of the depths of major landslide surfaces, the analysis of landslide evolution, and the development of hydrogeological models for landslide events [41][42][43][44][45][46][47][48][49][50][51][52][53]. It can also be used to differentiate loess landslides, as shown in Figure 2 regarding the differentiation of rock landslides by wave velocity.…”

The stability of loess landslides affects the production and livelihood of the people in its vicinity. The stability of loess landslides is influenced by various factors, including internal structure, collapsibility, water content, and shear strength. The landslide stability of loesses can be analyzed by several geophysical methods, such as seismic refraction tomography (SRT), electrical resistivity tomography (ERT), micro-seismic technology, and ground penetrating radar (GPR). Geotechnical tests (compression and shear tests) and remote sensing techniques (Global Navigation Satellite System (GNSS), Interferometric Synthetic Aperture Radar (InSAR) and airborne 3D laser technology) are used for studying the landslide stability of loesses as well. Some of the methods above can measure parameters (e.g., fractures, water content, shear strength, creep) which influence the stability of loess landslides, while other methods qualitatively indicate the influencing factors. Integrating parameters measured by different methods, minimizing disturbances to landslides, and assessing landslide stability are important steps in studying landslide hazards. This paper comprehensively introduces the methods used in recent studies on the landslide stability of loesses and summarizes the factors which affect the landslide stability. Furthermore, the relationships between different parameters and methods are examined. This paper enhances comprehension of the underlying mechanisms of the stability of loess landslides to diminish disastrous consequences.

Electrical resistivity tomography is a non-destructive and efficient geophysical exploration method that can effectively reveal the geological structure and sliding surface characteristics inside landslide bodies. This is crucial for analyzing the stability of landslides and managing associated risks. This study focuses on the Lijiazu landslide in Zhuzhou City, Hunan Province, employing the electrical resistivity tomography method to detect effectively the surrounding area of the landslide. The resistivity data of the deep strata were obtained, and the corresponding geophysical characteristics are inverted. At the same time, combined with the existing drilling data, the electrical structure of the landslide body is discussed in detail. The inversion results reveal significant vertical variations in the landslide body’s resistivity, reflecting changes in rock and soil physical properties. Combined with geological data analysis, it can be concluded that the sliding surface is located in the sandy shale formation. Meanwhile, by integrating various geological data, we can conclude that the landslide is currently in a creeping stage. During the rainy season, with rainfall infiltration, the landslide will further develop, posing a risk of instability. It should be promptly addressed through appropriate remediation measures. Finally, based on the results of two-dimensional inversion, this article constructs a three-dimensional surface morphology of the landslide body, which can more intuitively compare and observe the internal structure and material composition of the landslide body. This also serves as a foundation for the subsequent management and stability assessment of landslides, while also paving the way for exploring new perspectives on the formation mechanisms and theories of landslides.

“…In recent years, using comprehensive exploration geophysical methods to carry out geological exploration has gradually become the norm (Bedair et al, 2021). The two geophysical methods used in this paper are multichannel analysis of surface waves (MASW) and electrical resistivity tomography (ERT), both have proved to be the efficient methods for landslide research among all geophysical methods, (Loke et al, 2015;Khalil et al, 2017;Marciniak et al, 2021). We use a combination of these two methods because a single geophysical method is non-unique in the interpretation of the results, which limit us to make accurate judgments about the subsurface structural information obtained from the inversion, MASW is a good match for ERT in terms of detection depth, and the combination of their inversion results can provide more complete information to the subsurface structural of the landslide.…”

Natural disasters such as debris flow caused by earthquakes seriously threaten the local infrastructure and economy, as well as the lives of people in the area. As the material source of debris flow, it has significance to accurately and effectively study the underground structure of the landslide to prevent debris flow disasters. A landslide has a complex structural system, and its underground characteristics play an important role in its stability. The early identification of fracture surfaces and unstable bodies, and assessment of potential hazards are essential for prevention and protection. The research object of this paper is a landslide that occurred in Yige Village, Xianshui Town, Daofu County, which is on the Xianshui River Earthquake Zone, an area subject to frequent earthquakes. In western Sichuan, the frequent occurrence of landslides has caused considerable economic losses. Developing methods for efficient and accurate risk assessment is a top priority. The Daofu landslide is a typical example of a landslide directly threatening the road below and forming a debris flow channel. The lithology is composed of Jurassic sedimentary rocks, such as marl and clay, covered by limestone. In this study, we combined traditional methods (drilling and field investigation) with two geophysical techniques, multichannel analysis of surface waves (MASW) and electrical resistivity tomography (ERT) to effectively determine the electrical characteristics, velocity characteristics and spatial structure of the landslide. It is found that the buried depth of the sliding surface of the landslide is about 16–20 m. The sliding body above the sliding surface forms a low velocity and low resistivity Quaternary cover. The rock mass below the sliding surface is Triassic Zhuwo Formation sandstone and slate with high velocity and high resistivity. According to comprehensive analysis, the landslide lacks sufficient stability under rainstorm. Our study shows that the use of MASW and ERT can quickly and effectively characterize the subsurface of landslides to assess landslide risk and prevent debris flow hazards.
