“…When seismic waves encounter inhomogeneities they may scatter. Scattered surface waves can be used for locating and characterizing near-surface structures at engineering scale (e.g., Grandjean and Leparoux, 2004;Xia et al, 2007;Harmankaya et al, 2013) and at exploration and global scale (e.g., Snieder and Nolet, 1987;Rickers et al, 2012). Here, we utilize only scattered surface waves at the receivers due to one source at the surface and perform correlation.…”

“…Here, we utilize only scattered surface waves at the receivers due to one source at the surface and perform correlation. Interpreting this process from the point of view of seismic interferometry, when one source is present and only scattered fields are correlated, only non-physical (ghost) arrivals will be retrieved (Harmankaya et al, 2013, Mikesell et al, 2009Meles and Curtis, 2013). Here, we use such correlations of scattered arrivals to estimate the location of scatterers.…”

SUMMARYInspired by a technique called seismic interferometry, we estimate the location of scatterers in a scaled model, where many near-surface scatterers are present. We isolate the scattered wavefield and evaluate correlation of scattered waves at different receiver locations. The cross-correlation eliminates the travel path between a source and a scatterer, making the estimation of the scatterers' locations dependent only on properties between the receivers and the scatterer. We illustrate the potential of this method by locating scatterers with ultrasonic laboratory measurements of scattered Rayleigh waves recorded on two parallel and orthogonal lines of receivers. As near-surface scatterers are potential weak zones and may pose risk for the environment, to mitigate geo and environmental hazards, this method can be an efficient alternative that can be used in detection of such structures.

“…The method proposed by Harmankaya et al (2013) is applied to seismic field data collected above an a priori known tunnel by BRGM (Bureau de Recherche Géologique et Minière) at Jargeau site, Loiret, France (Leparoux et al, 2000). The data consists of multiple shot gathers recorded along a 63-metrelong profile with 24 channel receivers.…”

“…These heterogeneities may scatter seismic waves when the dominant seismic wavelength is close to the size of the heterogeneities. Scattered waves can be used for locating and characterizing near-surface structures in engineering, exploration and global seismology (e.g., Grandjean and Leparoux, 2004;Xia et al, 2007;Harmankaya et al, 2013;Snieder and Nolet, 1987;Rickers et al, 2012). In our method, we use correlations of scattered arrivals to estimate the location of scatterers, but we only correlate isolated scattered waves due to one source at the surface.…”

The investigation of near‐surface scatterers, such as cavities, tunnels, abandoned mine shafts, and buried objects, is important to mitigate geohazards and environmental hazards. By inversion of travel times of cross‐correlated scattered waves, due to the incident Rayleigh waves, we estimate the location of a near‐surface tunnel from seismic field data. The cross correlation eliminates the travel path between a source and a scatterer, thus eliminating the need to know the position of the source, making the estimation of the scatterers' locations dependent only on properties between the receivers and the scatterer. First time using a numerically verified method on seismic field data, we show the potential of the method for estimating the location of a buried scatterer.
