Abstract :
The results and methods used in an experimental study on the passive seismic detection of underground tunnels are presented. The study included the characterization of some man-made activities within tunnels, the use of triangulation and seismic imaging as source localization techniques, and preliminary results of using a laser Doppler vibrometer for detecting vibrational activities within a tunnel. Some properties of the ground that pertain to the detection of tunnels and the experimental methods used to extract them are also described.
