Abstract As volcanoes are closely related to the living environment of humans, in particular via natural hazards and geothermal energy, scientific studies on volcanic edifice structures are required. Ulleung Island is a Quaternary volcanic island loc

Clays in fault zones have low electrical resistivity, making electrical resistivity tomography (ERT) effective for fault investigations. However, traditional ERT inversion methods struggle to find a unique solution and produce unstable results owing

In order to interpret field data from small-loop electromagnetic (EM) instruments with fixed source–receiver separation, 1D inversion method is commonly used due to its efficiency with regard to computation costs. This application of 1D inversion i

Ground-penetrating radar (GPR) surveys are frequently used to delineate the distribution of subsurface water. This paper demonstrates that GPR is suitable for detecting water leakage from underground construction areas because it produces detailed im

In tunnel construction, the information regarding rock mass quality and the distribution of weak zones is crucial for economical tunnel design and to ensure safety. Usually, the rock mass grade is estimated by observing recovered cores obtained by dr

Small-loop EM and GPR surveys were carried out for imaging the ground water to detect water leak from a mortar wall buried in an artificial sandy test field. Both methods are suitable for surveys of small-scale water leaks. Apparent resistivity distr

Geophysical well logging is frequently applied to the geotechnical investigation of the subsurface for the construction of tunnel and bridges. The advantage of geophysical well logging lies in that the measurements of in situ physical properties of r
