| Outline of Final Research Achievements |
We identified concealed or inferred active faults very close to the most important tow remains, (Yoshinogari site on the Saga plain and Sannai-Maruyama site on the Aomori plain, respectively), based on 3D maps and high resolution stereo-pair of air photo interpretations. In order to clarifying subsurface image and structure of these inferred faults, we conducted high-resolution shallow seismic reflection surveying by using Land Streamer System around the Yoshinogari remains in Kyusyu. These active faults were more likely to be active in Holocene time, from Jomon period to the Yayoi period. What kind of influence did past culture come under by natural disaster? The problem of future disaster prevention measures will become clear by knowing the past.
