Outline of Final Research Achievements

In this study, we observed depth profile of salinity and temperature along Nankai Trough and Japan Trench around Hokkaido, which enables us to evaluate the oceanic fluctuation component for hydraulic pressure on the seafloor. From our analyses, we demonstrated that impact of sea surface height change driven by Kuroshio large meander have time lag about one month to the seafloor, and that unreasonable signal during the postseismic deformation of the 2003 Tokachi earthquake is explained from a meso-scale eddy observed from line observational data.

Academic Significance and Societal Importance of the Research Achievements

海底圧力計は、海洋変動を捉えるだけでなく、津波や海底地殻変動を検知する上でも有用であるため、地震分野ではケーブル式観測網が世界各地で敷設されている。本研究では、海底圧力値から海底地殻変動と海洋変動を分離するため、南海トラフ沿いと千島海溝沿いに設置されたケーブル式観測網の連続データの新たな活用を試みた。その結果、黒潮大蛇行の発生過程の理解が深まり、十勝沖地震の余効変動過程を従来よりも高精度で推定することが出来た。このことは、海洋温暖化や地震・津波の防災対策など、国民一般の社会対策の高度化につながるものである。
