Outline of Research at the Start

日本列島のテクトニクスや地殻変動は、太平洋プレートの沈み込みを中心に据えて描かれることが多い。しかし、東アジアの一部という広域的な視点に立てば、日本列島はインド亜大陸のヒマラヤでの衝突が中国や極東ロシアなどに波及した結果の終着点として位置づけられる。本研究では、東アジア全体の現在の地殻変動場を統一的な観測データから明らかにすることを試みる。中国・ロシア極東・日本などのGNSS観測から得られるデータを統合し、東アジア全体の地殻変動を明らかにすることで、東アジアの広域テクトニクスの中での日本列島の位置づけを考える。

Outline of Final Research Achievements

The GNSS observation network has been dramatically developed in the East Asian countries. We evaluated and arranged crustal deformation data across multiple countries in a unified reference coordinate system. Spatio-temporal crustal deformation field in east Asia as drawn by our research clarified the Japanese Islands has been widely affected by complex lasting post-seismic deformation after large earthquakes. This result request to evaluate above effects for plate coupling estimation on subduction zones along the Pacific ocean of Japanese Islands.

Academic Significance and Societal Importance of the Research Achievements

これまで、日本列島の地殻変動場は日本列島内に基準点を設定し、そこからの相対変位として表現されてきた。このため、2011年東北地方太平洋沖地震をはじめとした巨大地震が引き起こす長期広域的な影響の評価が難しく、プレート間固着の推定等に系統的な誤差が混入している可能性があった。本研究で示された、日本列島内ではない基準座標系を設ける方式を導入することにより、列島規模の長期広域的な地殻変動場を評価することが可能となり、沈み込み帯でのプレート間固着率や日本列島内のひずみ蓄積状況のモニタリングの高精度化を始めとした地震発生評価にも貢献することが期待される結果である。
