What is it about?
This study presents new seismic imaging techniques using seismic resonance waves to detect and locate an air-filled vertical water collection shaft. The approach is based on active-source seismic data and ambient noise data. The techniques do not require knowledge of the physical parameters of the subsurface and may be applied to other classes of near-surface strong inhomogeneities, such as vertical mine shafts, karst, tunnels, or near-surface cavities.

Why is it important?
Air-filled voids, such as karst or cavities, in the Earth near-surface can pose hazards to humans. We present new techniques of finding such cavities using resonance seismic waves.
Perspectives
The techniques were developed with the intention of being used by non-technical users to aid in their search for subterranean cavities.
