This paper presents an overview of the strengths and limitations of existing and emerging
geophysical tools for landform studies. The objectives are to discuss recent technical …

We have developed an application of 2D time-domain waveform tomography for detection of
embedded sinkholes and anomalies. The measured seismic surface wavefields were …

Anthropogenic cavities excavated just beneath the walkable floor (about 1–6 m depth) are
present in many ancient urban centres, particularly in Europe and along the Mediterranean …

Site characterization for design of deep foundations is very crucial, as unanticipated site
conditions still represent significant problems and disputes occur during construction …

Sinkholes and cavities can represent serious hazards to human safety and urban
infrastructures, cause roadbed subsidence, and so on. It is therefore essential to evaluate …

Structures formed by advanced manufacturing methods increasingly require nondestructive
characterization to enable efficient fabrication and to ensure performance targets are met …

The paper presents a technique to invert two-dimensional (2D) full wavefields using
simulated annealing and a finite-difference solution of the 2D elastic wave equation in the …

Recent research on earthquake disasters has provided evidence that Rayleigh waves play a
crucial role in causing damage to both underground and surface structures during …

Caverns in hard limestone form natural karstic features. Surveying, detecting, and managing
caverns are valuable as they provide an accurate and reliable understanding of the …

High-frequency Rayleigh-wave method plays an important role in the near-surface seismic
investigation. Rayleigh wave propagates along the free surface, and its propagation is …
