From page 56...
... 56 Abstract Underground Imaging Technologies (UIT) is developing a technology that makes use of seismic shear waves (S-waves)
From page 57...
... 57 Additional notes: Previous attempts at locating pipes and tunnels with reflection seismology have identified trade-offs between only a limited set of survey characteristics that influence imaging success. Technically successful surveys use large numbers of sources and receivers with extensive processing, resulting in a prohibitive time and cost for utility location.
