Session LanguageJ
ScopeWe have organized sessions in the JpGU meeting on nuclear power plants in Japan mainly from a viewpoint of earthquake science since 2013. Topics in the sessions include risks of nuclear power plants related to earthquakes, volcanic activities and tsunamis, as well as the problem of communication gap between scientists and engineers on those risks.
In the 2019 JpGU meeting, we propose the session that focuses mainly safety against inland earthquakes. For a last decade, strong inland earthquakes occurred, such 2007 Off Niigata-Chuetsu earthquake (M6.8), 2008 Iwate-Miyagi earthquake (M6.9), 2016 Kumamoto earthquake, which did damage to regions near the earthquakes. Recently, 2018 Hokkaido east Iburi earthquake (M6.7) gave devastating effects to the epicentral area. Considering the high activity of inland earthquakes, it is important to reconsider the safety measures of nuclear power plants against strong inland earthquakes.
We would encourage discussions from a broad viewpoint across science and engineering, such as evaluation of strong motion due to inland earthquake and anti-seismic capability of nuclear power plants.
We welcome papers of other topics relevant to relationship of earthquake science and nuclear power plants, too.
