Outline of Research at the Start

紀伊半島~南海トラフ熊野沖をテストフィールドに海域から陸域、浅部から深部までの地球物理学的観測と地質学的物質科学を融合し、Slow-to-Fast地震が発生する場(Slow-to-Fast地震発生帯)の構造を解剖学的に理解する。地下構造の精密なイメージングと物性変化のモニタリング、岩石中のSlow/Fast地震履歴・流体痕跡の解読と化学分析・実験・シミュレーションの最新の知見を融合して、Slow-to-Fast地震発生帯の状態の変化過程、特に流体の役割を明らかにするとともに、その形成と発展をマルチ時空間スケールでモデリングする。

Outline of Annual Research Achievements

1.浅部観測研究: 南海トラフに設置された孔内地震計・海底地震計の常時ノイズ記録から、プレート境界近傍で反射するS波の定常的抽出に成功した。2016年に近傍で発生したM5.9の地震後に反射S波の振幅が増大しており、流体移動の影響を議論した。南海トラフ中部の反射法地震探査データから、プレート境界の上面形状の構造的な特徴と、既往研究のスロー地震分布及びプレート固着状態との関連について検討した。日向灘において上盤プレート内に流体の通り道と解釈される低速度帯を発見した。海山沈み込みとスロー地震の関係解明を目的とした国際科学掘削計画提案が採択され、国際会合を実施した。
2.深部観測研究: 豊後水道の長期的スロースリップ、スラブ内地震と相似地震の連動性について調べ、長期的スロースリップが発生する1年前に海洋プレート内部で応力場が変化することを見出した。
3.浅部物質研究: 四国および紀伊半島四万十帯で発達する鉱物脈を対象とした野外調査を行い、地震周期に伴う亀裂を介した流体の排出や亀裂の鉱物充填によって上盤プレートの透水性が時間変化することを解明した。地質構造発達のモデル化に向けた大型アナログ実験装置を導入し、実験パラメータの整備をしつつ変位量の違いによるくさび変形の違いを明らかにした。断層岩マルチスケール解析のための微小部XRF分析装置を導入した。
4. 深部物質研究: 陸上付加体メランジュ層北縁断層のカタクレーサイトにおいて、石英の結晶塑性変形を確認した。2021年度開発した岩石の堆積変化推定法を用いて、フランシスカン帯において流体移動による物質移動を定量的に見積もり、有意な体積増加を示した。深部スロー地震と同等な深さにおいて沈み込み帯境界領域における応力を推定するために三波川変成帯から採取された岩石の分析を行った。地質体の経験した最高被熱温度測定のためのラマン分光分析装置を導入した。

Current Status of Research Progress
Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

新型コロナウィルス感染症の状況により海外出張予定が延期になるなどの影響があったものの、新規装置の立ち上げやデータの取得・解析、共同研究などがおおむね順調に進行した。

Strategy for Future Research Activity

2022年度に導入した大型備品の立ち上げを終えて活用するとともに、計画研究内での共同研究や、領域内での共同研究を促進する。公募研究との連携を図る。
