| Research Abstract |
Shikoku fears heavy damage during the Nankai Earthquake, which is due to hit this region in next 30-50 years. Although tsunami is particularly feared of, the potentials of geo-disasters are equally important. Not only liquefaction of coastal areas in Kochi and Tokushima plains and landslides in mountainous areas, but discontinued road network is also expected to affect people's life in the disaster-hit areas. If the Nankai Earthquake takes place right at present, the reconstruction of Route 32 is supposed take more than one month, that of Route 33 is estimated at a few weeks, and that for Route 56 and JR Yosan Line is yet to be estimated. This will cause isolation of Kochi Prefecture from terrestrial-route perspectives. At the same time, human settlements over the remote mountains will also be isolated, and the scattered cultural heritage sites of Shikoku will also be damaged. All this in background, hazard assessment of the road network in Shikoku during the Nankai Earthquake has been made and hazard maps have been prepared in this study. The ground dynamics of the cultural heritages sites, particularly, the Shikoku 88-Pilgrimage Temples, has also been investigated and elucidated with the help of microtremor survey.
