| Abstract;An array observation of self-potential variations has been carried out for more than 10 years in the observation tunnel of the Hokuriku observatory, Fukui prefecture. By this observation, self-potential variations caused by the leakage current from the DC electric railway are observed. We planned to analyze the change of tectonic conditions by comparing the leakage current wave forms of two or more stations. For this purpose, a high sampling observation equipments are settled in the tunnel. The observation is not fully started yet. So, in this paper, the former results and our future plan will be described. (author abst.) |
