Offshore extension of the Kakuda-Yahiko fault and its fault-propagating fold are investigated based on combination of high-resolution seismic surveys and sedimentary analysis to evaluate their Holocene activity. High-resolution multi-channel seismic surveys with the boomer sonar (13 lines) and high-frequency seismic survey with the chirp sonar (3 lines) ran across the fault line and its extension, and provided us sharp imageries of stratigraphic succession formed after the last lowstand. We can clearly recognize progressive deformation at the eastern-wing of the fault-propagating fold in the observed succession. To determine actual ages of the seismic strata, we measured radiocarbon dates from sedimentary cores obtained by 2 offshore borings and 2 vibro-coring surveys. Based on deformation of strata between 10.8 ka and 4.7 ka, averaged vertical slip rate was figured out to be 2.1 m/ky. On the other hand, we investigated temporal changes of accumulation rates at both the upthrown and the downthrown sides of the fault. Dynamic changes of the accumulation rates indicate that there were approximately 3 events at least during the last 10.8 ky and the averaged vertical slip rate was 3.0 m/ky during the period. Another focus of our study is on the latest activity of the fault. On the fault-propagating fold, we distinguished the uppermost strata younger than 0.9 ka without any deformation from these older than 2.1 ka with obvious fault deformation based on the profile obtained by the chirp-sonar seismic survey. These observations affirm that the latest event should have occurred between 0.9 ka and 2.1 ka. Furthermore, structural analysis on the deformed strata of 2.1 ka indicates that throw of the fault at the latest "single" activity was ca. 7.5 m. This study successfully demonstrated that set of parameters about the active fault including average slip rate, activity history, timing of the latest event, and associate surface displacement per activity of the fault could be elaborated from series of offshore active fault surveys.

Abstract: 地震や累積的な断層運動は,地表に変位を生じさせる.この地表変位から地下の断層形状を推定することは,地震被害想定の観点からは重要な課題の一つである.断層形状を推定する従来手法として,バランス断面法とOkadaの食い違い理論に基づく手法がある.これらの手法は,褶曲が地表で確認できない場合や,共役断層を含む複数の断層が想定される場合には正確に断層形状を推定することは困難である場合が多い.本研究では以上の欠点を補う手法として,有限要素法と位相最適化手法を組み合わせた断層形状推定手法を新たに提案する.断層形状推定問題を最適化問題として定式化し,いくつかの計算例を通じて開発手法の精度検証を行った.結果,開発手法は一定以上の精度で断層形状を推定できることを確認した.

Abstract:チベット高地に点在する湖の周囲には数多くの湖段丘が分布する.湖の水位が下がると地殻を隆起させる浮力が生じる.隆起が起こるために中部地殻における岩石の流動も必要である.流動のタイムスケールは、湖の盆地の幾何学と中部地殻の粘性で決まる.盆地の形は既知であるので,粘性は段丘の隆起量及び隆起のかかった時間から導出できる. 段丘の隆起量は湖の中央が最大であり,一般に同じ段丘は場所によって中央からの距離が異なる.よって,湖の地盤の隆起が起こると段丘は緩やかに傾斜することになる.チベットで最大級の湖であるナムツォ湖周辺の段丘の高さをキネマティックGPSによる精密測量により決定し,段丘に付着したトゥファの14C年代測定を行った.その結果,ナムツォ地域の中部地殻は10^20 Pa s以上の粘性を持つという制約が得られた.一般的に予想されるチベット中部地殻における低粘性層の存在を再検討する必要が出てきた.
