| Research Abstract |
The purpose of the research is to evaluate the millennium tsunami hazard ,which is a low frequency giant tsunami disaster which occurs once in about 1000 years, by complementing based on scientific techniques, such as geology, sedimentology, topography, and seismology, in addition to the historical fact and documents in literatures. Millennium tsunami hazard evaluation was carried out in Okinawa and the Tohoku district. First, a possibility that 850yrBP and two terms of 1100 yrBP would be suggested by the investigation and analysis of a coral fossil (tsunami stone) which were launched from tsunami in Yaeyama Islands in addition to the 1771 Meiwa tsunami was shown. Furthermore, interdisciplinary investigation is conducted in Sendai plane that 1260yrBP and 2050 yrBP would is added to the 869 Jogan earthquake. Examination of the tsunami damage function etc. which were obtained by the 2011 Great East Japan Earthquake was also carried out.
