Abstract
Several prospecting methods have been used to detect deep seated small tunnel in Korea. Tunnel interpretation of seismic method has been performed mainly by wave traveltime inversion method. But it often gives inacurate solution for the exact tunnel position because of the short distance between two measuring boreholes and picking errors of first arrivals. In this study, "error tomogram" was proposed to detect tunnel position and applied to theoretical and field dat using multi-source amplitude data.
