“…Due to the high resolution capacity of the method it has been widely used for hydrogeological and environmental purposes since the 1980s (Jongerius and Helbig, 1988;Büker et al, 1998;Steeples et al, 1995;Pugin et al, 1999;Jørgensen et al, 2003a), and the method is steadily undergoing refinements in order to enhance efficiency and data quality. In this process various systems and different setups have been studied (Miller et al, 1986(Miller et al, , 1992Steeples and Miller, 1990;van der Veen et al, 2000), and comprehensive evolution of data handling and processing has taken place (Steeples and Miller, 1990;Büker et al, 1998;Pugin and Pullan, 2000).…”

Airborne electromagnetic methods (AEM) are used extensively in groundwater investigations, often in combination with high-resolution seismic data. Despite the frequent use of this mapping strategy, only a few cases are found in the literature. In this study, comparisons and interpretations were made based on AEM (SkyTEM) and high-resolution seismic data from an area covering 10 km 2 in the western part of Denmark. As support for the interpretations, an exploration well was drilled to provide lithological and logging information in the form of resistivity and vertical seismic profiling. Based on the resistivity log, synthetic SkyTEM responses were calculated with a varying number of gate-times in order to illustrate the effect of the noise-level. At the exploration well geophysical data were compared to the lithological log; in general there is good agreement. The same tendency was recognised when SkyTEM results from the area were superposed onto seismic sections. Comprehensive geological knowledge is necessary in order to introduce layer boundaries from one method interactively in the data handling of the other. However, in cases where resistivity transitions are positively correlated to reflections, SkyTEM data supports the interpretation of weak reflections, and can also support the correlation of reflections both internally and between seismic lines. Besides contributing lithological information, the AEM survey provides gross three-dimensional structural information, whereas seismic data contributes with more detailed structural information in two dimensions.

“…Body wave seismic techniques have not been extensively used due to survey costs and resolution requirements. With equipment improvements and technique developments and the wealth of information contained in the seismic wavefield (body waves and surface waves), seismic measurement or imaging data are routinely underutilized (Steeples et al, 1995).…”

A 10 ft wide and 10 ft deep sinkhole that catastrophically formed approximately 120 ft upstream of the crest of Clearwater Dam in southeastern Missouri was the target of a high-resolution seismic imaging program including reflection, surface wave analysis, and crosshole tomography. The primary goals were to determine the general subsidence geometry and integrity of the core and help ascertain the involvement of bedrock and native alluvium beneath this earthen dam. Reflection data from this survey possess excellent frequency content (dominant >150 Hz) and provide high-resolution images of layers within the pervious shell. Using tightly spaced surface wave profiles, an elongated low shear-wave velocity chimney-like feature was delineated and interpreted to represent the root of the sinkhole. Based on seismic, construction, drill, and borehole tracer data, a borehole geophysics program was designed to identify fractures/joints that might provide seepage pathways. Crosshole seismic data detected a large low-velocity zone within the bedrock and an associated low-velocity zone within the pervious fill consistent with the surface seismic interpretations. A comprehensive appraisal of the risk this disturbed zone represents to the overall integrity of the dam and whether it is a symptom of a larger, yet undetermined subsurface leaching problem is being developed.

“…The high cost associated with acquiring and processing seismic reflection data, especially for 3D imaging, has traditionally limited its use to the oil industry. Nevertheless, advances in microelectronics in the early 1980s enabled the development of cost-effective seismographs and microcomputers, opening new possibilities for reflection seismology in a range of fields, from deep crustal exploration to civil engineering site investigations [7]. As a result, this technique is now used successfully in various fields, including deep crustal exploration, groundwater resource assessment, and civil engineering site investigations [8].…”

In this paper, seismic exploration methods are reviewed with a particular emphasis on the use of the reflection seismology to investigate the subsurface structures and characterize active faults. The paper provides a descriptive overview, intended for a non-specialist audience, of the methods and of their recent developments aimed at improving the resolution, accuracy, and computational efficiency of seismic imaging. Techniques such as seismic ray tomography, full-waveform inversion and pre-stack depth migration are briefly introduced, highlighting their potential applications in structural geology studies. The main seismic attributes that have become increasingly important in the interpretation of faults and fractures are also presented, along with some examples of application. Finally, some case studies of active fault characterization are discussed. From these examples, the crucial role played nowadays by the seismic exploration methods for structural studies and for active fault characterization is evident.
