Recent realization of various utilization of underground space is promoting the development of advanced method for surveying joints and some other geological conditions. Geotomograghy technique-seismic, resistivity and electromagnetic tomography - is being studied as the prospecting technique to investigate geological condition between the boreholes. In order to establish the geotomograghy technique to synthetically evaluate the geological; condition based on the combination of each tomography, the application of electromagnetic tomography is evaluated. This paper describes the result of the fundamental tests in a water tank and the in-situ tests in the rock mass by the borehole radar system. First of all, the electromagnetic tomography test in a water tank is carried out to quantify the characteristics of the instruments. Secondly, in-situ test is conducted to detect the well located fault in rhyolitic rock mass, where the data under two frequencies (80MHZ, 150MHZ) are analized in terms of both velocity and attenuation. The results are compared to that from seismic tomography method to find the superiority in resolution of electromagnetic tomography. キーワード（英）： - 記事区分： - 区分 　　　委員会論文集
