The seismic ground characteristics estimated by micro-tremors measurements and weak earthquake observation at the arrays set up in Kushiro district in Japan have been examined. It is suggested from these examinations that the micro-tremors measurements are usable as an effective tool to estimate the seismic site-specific characteristics. In this paper, the reliability of the micro-tremors measurements as a tool of estimating site-specific characteristics by comparing the estimation results at the arrays in the Kushiro and at another arrays in Kansai district are examined. These arrays are located in different conditions with respect to geological structure and micro-tremors source effect.
