abstract = {Determining the structure and evolution of landslides is crucial for geophysical hazard assessment. In this study, we employed an approach integrating the methodologies of multi-channel analysis of surface waves (MASW) and electrical conductivity to image temporal and spatial changes within a landslide in southern Poland. The area, located in the Outer Carpathians, experiences significant climate fluctuations, compounded by anthropogenic activities such as recreational skiing requiring artificial snow. Our combined seismic and electrical methods techniques reveal the landslide's susceptibility to environmental factors on both annual and seasonal scales. Additional analysis, including data clustering and remote sensing, identifies three distinct landslide zones with varying vulnerability to natural and anthropogenic influences. While focusing on a specific area, our approach has global applicability to similar mass movements. This research addresses a gap in understanding time-dependent geophysical observations of moisture-driven landslides, providing valuable insights for hazard identification and mitigation strategies. © 2024 The Authors},

Additionally, synthetic forward modelling is presented as a tool for supporting seismic anisotropy studies. The geophysical measurements of cracks allowed to recognise the fracturing of a granite rock mass in a Paleozoic granite quarry (Strzegom; Poland) and a dolomite rock mass in a Triassic dolomite quarry (Podleśna; Poland). Application of the forward modelling supports the interpretation of seismic methods, simplifying data processing and verifying the final results based on data from difficult seismic conditions. As a result of direct measurements, two crack systems were determined in granite rock mass: NNE-SSW and NNW-SSE, and two in dolomite rock mass: NNE-SSW and NW-SE. Furthermore, the numerical results show the relationship between the highest values of P- and S-wave velocities and separated crack systems which allowed an unequivocal interpretation of the direction of stress, resulting in the deformations.

abstract = {Landslides, as one of the main problems in mountainous areas, are a challenging issue for modern geophysics. The triggers that cause these phenomena are diverse (including geological; geomorphological; and hydrological conditions; climatic factors; and earthquakes) and can occur in conjunction with each other. Human activity is also relevant, undoubtedly contributing to the intensification of landslide phenomena. One of these is the production of artificial snow on ski slopes. This paper presents a multimethod approach for imaging the landslide structure in Cisiec, in southwestern Poland, where such a situation occurs. In the presented work, the integration of remote sensing with multi-method geophysical imaging was used to visualize landslide zones, and to estimate ground motion. To verify the uncertainty of the obtained data, the combination of electrical resistivity tomography (ERT), multi-channel analysis of surface waves (MASW), and seismic refraction method (SRT) was supported by synthetic modeling. Using geophysical data with accurate GPS-based topography and a terrestrial laser scanning-based digital terrain model (DTM), it was possible to model the spatial variability and surface area of the landslide more precisely, as well as to estimate the velocity field in the nearest surface more accurately. The final result shows displacement up to 1 m on the ground surface visible on the DTM models, while the geophysical methods confirm the change in internal structure. The proposed methodology is fast, cost-effective, and can be used to image the structure of landslides, where the shallowest parts are usually complex and thus difficult to observe seismically. © 2022 by the authors.},

In this study, we demonstrate the application of multimethod geophysical reconnaissance, combining electrical resistivity tomography (ERT), induced polarisation (ERT-IP), seismic refraction tomography (SRT), and multichannel analysis of surface waves (MASW), to identify the subsurface karst structures at two sites in the Silesian District, Poland. This methodology allowed the identification of the geological structure to a depth of up to 40 m, which exceeds the requirements for geotechnical reconnaissance. At site 1, Niedzieliska, a 30-m-wide and 20-m-deep structure, filled with younger sediments, was interpreted as a karst sinkhole. At site 2, Tucznawa, a 180-m-wide fault zone overlain with suffusion-susceptible sediments was identified.

abstract = {Soil contamination with trace elements in mining areas still remains an urgent research problem due to their negative environmental impact that needs to be assessed. Despite the wide application of the electrical resistivity tomography (ERT) method to different environmental problems, it continually remains methodologically challenging in soil contamination near waste dumps of post-metal historical mining. The aims of our study were: (1) to validate ERT measurements for detecting soil contamination by trace elements in the vicinity of a waste dump containing post-processing spoil from Zn-Pb ore smelting, (2) to determine the extent of soil contamination, and (3) to analyze the mineralogical, physical, and chemical properties of the soils affected. ERT enabled us to study the variability of electrical properties of soils, to locate the area of contamination, and to evaluate its spatial diversity in both. The impact of soil pollution is reflected on ERT cross-sections in the form of electrical resistivities that decrease with increasing depth and distance from the waste dump. The respective maximum contents of Zn, Pb and Cd in the soils were 28,903, 12,407, and 136 mg kg−1. The total concentration of trace elements in soils was the highest down to a depth of 0.25 m and decreased in the order: Zn > Pb > Cu > Cd > Tl > As > Cr > Ni. The electrical resistivities of the soil samples were negatively correlated with the silty and clayey fraction content (−0.78), specific electrical conductivity (−0.75), total trace element content (−0.67), organic matter content (−0.57), and gravimetric water content (−0.53). The results also indicate that the electrical properties of the topsoil depend directly on the type of mineral components. Hydrated iron sulphates, lead sulphates, water-bound in aluminosilicates, Fe oxides/hydroxides, and hydrated Fe, Zn, and Pb sulphates present in the soil all decrease its electrical resistivity. Our results show the impact of the mineralogical, physical, and chemical properties of the soils on the measured electrical resistivity and that including this information in the interpretation of ERT results enables non-invasive detailed determination of soil contamination by trace elements. © 2021 John Wiley & Sons, Ltd.},

Electrical Resistivity Tomography (ERT), Seismic Refraction Tomography (SRT), Multichannel Analysis of Surface Waves (MASW) and Ground Penetrating Radar (GPR) were the techniques used to characterize a waste dump in the town of Dąbrowa Górnicza (S Poland). GPR and SRT were the most difficult methods to use because of the dense vegetation, which attenuated the passage of electromagnetic and seismic waves to the ground. However, GPR did turn out to be an appropriate tool for characterizing variations in the surface cover. ERT, SRT and MASW clearly highlighted the transition between the waste deposit and the host sediments, and determined the approximate thickness of the waste deposits. With MASW, however, the waste type and the boundary between the waste layer and surface cover could not be delineated. In some places, the surface cover was identified using SRT. With both these methods, the problem with identification may be due to the small contrast in the S- and P-wave velocities through two kinds of waste (municipal and industrial), the thinness of the waste layer, and the considerable differentiation of the surface cover. The most accurate results regarding the waste deposits were obtained using ERT and different electrode spacings. ERT pinpointed the exact location of the stored waste, distinguished between the types of waste, and identified the soil cover. Data from shallow boreholes confirmed the interpretations of the methods. © 2021 Elsevier Ltd},

abstract = {Near-surface seismic surveys are often designed for surface wave and seismic tomographic analysis. In recent years, seismic imaging methods have been more frequently used at this scale. Recognition of near-surface structures using a single method is insufficient because of the ambiguity of the inversion problem. As a solution, the authors propose a multi-step approach, where several different seismic methods are used in a particular order, to achieve an optimal model. A multi-method approach allows utilisation of a whole spectrum of recorded data, even the elements that are treated as background noise in other techniques. In classical processing approach, information about data uncertainty is often omitted or used in the simplest way for the single method only. This work presents an updated approach to uncertainty analysis by transferring estimated uncertainty between processing steps. By assuming that every consecutively applied method is more certain, the authors were able to obtain accurate velocity fields for seismic imaging, as the main information received from the previous steps. Based on information from multiple methods, a seismic stack in the depth domain was created as a final result, with an estimate of uncertainty. © 2019 A. Marciniak et al.},

abstract = {The aim of this study is to determine the subsurface lithological variability and thickness of each metamorphic rocks unit by means of geophysical methods, which were presented within the framework of SEDIBUD. Research was performed on the ridge and the steep eastern slope of the Orlik massif (1204. m) in the Hrubý Jesenik range of the Eastern Sudetes, the Czech Republic. To obtain a spatial image of a geological rock mass, the non-invasive and relatively rapid method of electrical resistivity tomography (ERT) was used, which resulted in the creation of six profiles using the Dipole-Dipole and Wenner-Schlumberger arrays. As complementary methods, vertical electrical sounding (VES) and seismic refraction tomography were chosen. Fifteen measuring points along two profiles obtained by vertical electrical sounding allowed the determination of the following in the vertical section layers of different resistivity and thickness at direct points in contact primarily with Devonian quartzite rocks and weathered covers. In a series of field studies, a four-layered rock mass was examined in which the first layer is of fine-grained materials with medium- and large-size clasts, the second layer is quartzite, the third is gneiss and the fourth is phyllite. The five profiles measured by seismic refraction tomography made it possible to draw the boundary between the studied phyllites, gneisses and quartzites. In addition, geophysical surveys and the results of mineralogical composition analysis allowed us to determine the nature and thickness of the weathered layers present on the massif area, which, in the upper sections, are predominantly a clayey loam partially covered with blocks. The inclination of the slope is associated with an increase in the fraction of coarse material. The majority of the thickness of these layers is related to the local flattened surfaces and the presence of numerous streams, which contributed to the accumulation of the sediments that were also transported from the ridge area. This diversity indicates notably active slope processes during the Pleistocene. The results confirmed the usefulness of geophysical methods to identify the geological structure of rocks with highly variable lithology with faults and folding features. © 2014 Elsevier B.V.},

abstract = {This paper presents the relation between main crack systems and physical properties of carbonate rocks. The existence of cracks in a rock mass causes the reduction of seismic wave velocity, which is smaller in direction perpendicular to a crack plane than in direction parallel to it. This affects the occurrence of the anisotropy of seismic wave velocity, which is characteristic for rocks with preferred orientation of cracks. The existence of relationship between crack and seismic anisotropy allowed to use geophysical methods for determination of fracture density and orientation of crack systems. The research area is located in the south-east part of the Upper Silesian Trough. Tectonic observation and geophysical measurements was carried on the carbonate sequence on the both fold limbs building the Chrzanow-Wilkoszyn Syncline, originated during the Early Cimmerian movements, in the Upper Triassic - Middle Jurassic period. It was measured seismic waves velocity in the surface layers of rock mass and the strike azimuth and dip angle of cracks.The seismic anisotropy of the rock mass was done along radial profiles having common central point using P.A.S.I. Seismograph (Mod.16S24-N). Results of field measurements were interpreted to estimate components of crack and velocity tensors. Obtained outcomes allowed to compare the existing main crack systems on the both fold limbs with seismic measurements. Eventually we have shown that seismic measurements are useful tool to study the cracks anisotropy in rocks inaccessible for direct observations.},

abstract = {In fractured rock mass, the orientation of cracks causes anisotropy of different physical properties, including the permeability coefficient. In rocks where the permeability of rock matrix may be negligible, flow occurs mainly through the connected fractures, or fracture networks. The rock mass which contains fractures of this kind can be treated as a homogeneous anisotropic porous medium to formulate the permeability tensor. This can be possible owing to introduction of crack tensor which depends only on the aperture, size and orientation of the related cracks. The crack tensor is coaxial with the permeability tensor. The relation between the permeability tensor and the crack tensor enables us to utilize the measurement of anisotropy of seismic wave velocity to establish potential directions of underground water flow. © Springer-Verlag Berlin Heidelberg 2011.},

abstract = {The existence of cracks in a rock mass causes the reduction of seismic wave velocity and the anisotropy of seismic wave velocity, which is characteristic for rocks with preferred orientation of cracks. The present study concerns sedimentary rocks (sandstone; limestone) and igneous rocks (basalt; granite). Studying the relationship between seismic anisotropy and cracks anisotropy in rocks I was only interested in fractures perpendicular to the layering. This allowed me to calculate two-dimensional crack tensors and velocity tensors in planes parallel to the layer surface. An application of tensor calculus enables to take into account both geometry and orientation of cracks. The obtained results confirm that the directions of major axes of second-rank velocity tensor prove the relationship consistent with predictions of theoretical models. Owing to these dependences, seismic methods can be used to study the cracks anisotropy in rocks inaccessible for direct observations. © Versita Warsaw and Springer-Verlag Berlin Heidelberg 2008.},
