| Research Abstract |
Damage concentration of wooden structures exerted by middle class earthquakes has been observed. Most of damaged areas are rural and detailed soil structure, which is inevitable for analyses, can be hardly obtainable. Combination of subsurface structure evaluated by micro-tremor, soil non-linearity estimated by recorded ground motion, and computation with evaluated bedrock motion can explain concentration of earthquake ground motion. By applying this method to Anamizu town and Sakae village, which have little in common in terms of geography and data resources, generality of this method was revealed.
