[G03-P01] 3D digital models of stone monuments to hand down historical earthquakes in Tokushima Prefecture, Japan
Keywords:Earthquake and Tsunami stone monument, Tokushima Prefecture, digital archive, Nankai Trough Earthquake, Photoscan
This study constructed 3D digital models of the stone monuments for historical earthquakes in Tokushima Prefecture. Then we evaluated the application of the monument to earthquake and tsunami hazard and evacuation.To construct 3D model, we used the same method with that of the monument in Kochi Prefecture, reported by Tanikawa et al. (2017).
We constructed 3D models of nine stone monuments and two stone guideposts that record the maximum tsunami run-up height. Even though we did not discover any hidden/illegible messages on monument from the 3D models, we could make out the characters on monuments clearly. At present, we are constructing the database site that introduces the information and location of the monument in Kochi Prefecture through a map using “e-community platform (http://ecom-plat.jp/)” web system which was developed by National Research Institute for Earth Science and Disaster Prevention in Japan. In this database site, we plan to overlay the tsunami hazard map published by public institutes to confirm the relationship between the location of stone monument and tsunami inundation distribution. We also plan to combine the data of the monument in Tokushima Prefecture into the same database.
