It is effective to grasp earthquake ground motion in a city to reduce effects due to an earthquake. Therefore it is necessary to estimate earthquake ground motion of many sites where a seismograph is not installed. In this study, we observed the microtremor with 19 points including seismograph sites to estimate earthquake ground motion distribution in Kushiro city. Furthermore, using the horizontal-to-vertical (H/V) spectrum ratios of microtremor and the seismic record at the site, we estimated the SI values in Kushiro city and compared them with observed SI values. If the ground does not become a non-linear state by an earthquake, we can estimate the SI value using the proposed method.
