Detection of Clandestine Tunnels using Seismic Refraction and Electrical Resistivity Tomography

  • The detection of clandestine tunnels is a major issue along the U.S.-Mexico border. These tunnels provide access to illegal transportation of drugs, weapons, and people. This study tests the use of high resolution seismic refraction techniques and electrical resistivity tomography to detect tunnels. The target sites are (i) surrogate tunnel sites along an abandoned railway track in Oxford, MS, and (ii) a plugged clandestine tunnel that runs from Agua Prieta, MX, to a warehouse in Douglas, AZ. The results show that the use of seismic and electrical techniques can detect the presence of a tunnel anomaly and can increase reliability and confidence in the location of tunnels.
