[M-IS01] Tsunami deposit

convener:Daisuke Ishimura(Department of Geography, Tokyo Metropolitan University), Takashi Chiba(Faculty of Bioresource Sciences, Akita Prefectural University), Masaki Yamada(Department of Geology, Faculty of Science, Shinshu University), Takashi Ishizawa(International Research Institute of Disaster Science, Tohoku University)

The 2011 off the Pacific coast of Tohoku Earthquake and tsunami have an influence on the development of tsunami deposit research. After the tsunami, a lot of findings have been reported on various research fields. However, it is still uncertain how to use the tsunami deposit in the estimation of tsunami size and source and the risk assessment. In this session, we welcome researches from all aspect of sedimentary records of modern and paleo tsunamis both onshore and offshore, and numerical and experimental modeling studies for risk assessment. In addition, we also welcome other event deposits, such as flooding and storm surge, that they are considered to be important for discrimination of tsunami deposit.
