[T13-P-3]Methodology of 3D digital outcrop modelling for internal deformation structure analysis of sediments: an example of the lower Miocene Orido tuff member, Kamiichi-machi, Toyama Prefecture, central Japan
*Hiroyuki Arato, Kazuo Kaneko1, Shonen Kunika2, Yuzuru Yamamoto3, Koichi Hoyanagi4, Yasuhiro Yamada5, Kazuya Shiraishi6, Shun Chiyonobu7, Shun Chiyonobu8, Takeru Yoshimoto3, Yuki Sekiyama3 (1.

[T13-P-4]Experimental varification of a two-dimensional inverse model of turbidity current using a fully connected neural network.
*Seiya FUJISHIMA1, Hajime NARUSE1 (1. Graduate School of Science, Kyoto University)
[T13-P-5]Earthquake fault parameters of ancient tsunami that surged on Ishigaki island: Estimation based on the distribution of cave deposits

[T13-P-6]Are coastal boulders at Cape Chihiro, Tosashimizu City, Kochi Prefecture, tsunami boulders?
*Satoru IMAI1 (1. Shimane Nature Museum of Mt. Sanbe)
【ハイライト講演】本ポスター発表では，高知県土佐清水市の海岸に見られる巨礫群の離水時期を生物遺骸から推定している．さらに，タフォニの深さからその形成時間を推定することで，巨礫群の離水現象が津波による転動によって起きたことを論証し，南海トラフ歴史地震との関連性を示している．南海トラフの地震履歴を地質記録から明らかにする新たな切り口となるかもしれない．（ハイライト講演とは．．．）
[T13-P-7]Correlation of event deposit layers interbedded with the annually laminated sediments in Lake Ichinome-gata, Oga Peninsula.
*Atsuki Nagata1, Hiroto Kajita1, Takuto Ando2, Masahiro Minowa3, Koji Umeda1 (1. Hirosaki Univ., 2. Akita Univ., 3. Hokkaido Univ.)
【ハイライト講演】本ポスター発表では，年縞堆積物が形成されうる好条件下にある一ノ目潟の湖底から採取されたコア試料を分析し，年縞に挟まれた4つのイベント層を認定している．そして年縞から推定される年代から，それらを形成した要因たる地震や大雨災害を特定している．適用できる場所は限定されるが，自然災害の履歴をより詳細に解明する手法として注目したい．（ハイライト講演とは．．．）
