The latest multichannel seismic data from the Yap subduction zone is presented to investigate the Caroline Ridge fault system, developed by faulting and bending processes within the incoming oceanic plateau. We reveal that horst and graben structures exist along the entire incoming Caroline Ridge adjacent to the trench and that pervasive bending-related faults trending ~N30°E have developed subparallel to the trench. However, the widths of the horst and graben structures decrease gradually from north to south. The two-stage ancient abyssal hill fabrics overlap the incoming Caroline Ridge. Abyssal hill faults trending ~N65°W present large trench-ridge angles (85–90°); in the southern segment, abyssal hill faults trending ~N70°E have relatively low trench-ridge angles (~35–40°). From the Caroline Ridge to the horst and graben structures, the topography decreases, and slump bodies with deformed internal reflections have developed above an irregular reflector. Little stable pelagic sediment with horizontal reflectors accumulates on the horst and graben structures, suggesting that the faulting and bending processes involve long and intense tectonic processes that affect the sedimentary environment. The sedimentary strata and fault distributions differ between the North and South Caroline Ridge, which is primarily attributable to the different rifting processes. Furthermore, we propose that N65°W-trending ancient faults sufficiently decrease the yield strength of the incoming Caroline Ridge to facilitate the bending-related faulting. During subduction, the incoming North Caroline Ridge that has a large degree of rifting and the Sorol Trough, which has a thin crust, may resist less flexural bending and generate the wide horst and graben structures. The ancient faults and rifting model of incoming oceanic plateaus play a significant role in bending-related faulting

介绍了Yap俯冲带最新的多通道地震数据，以研究卡罗琳岭断裂系统，该系统是由传入海洋高原内的断层和弯曲过程形成的。我们发现，在整个临近沟槽的卡罗琳岭附近，都存在着and陷和grab陷的构造，趋势为大约N30°E的普遍与弯曲有关的断层已经发展到与沟槽平行。但是，地上部分和抓地结构的宽度从北向南逐渐减小。两阶段的古代深渊丘陵面料与即将到来的Caroline Ridge重叠。倾向〜N65°W的深海山体断层表现出较大的沟脊角（85-90°）。在南部地区，趋向于〜N70°E的深海山体断层具有相对较低的沟脊角（〜35–40°）。从Caroline Ridge到霍斯特和and堡建筑，地形减小，内部反射变形的坍落体在不规则反射器上方形成。带有水平反射器的稳定的上层沉积物很少堆积在地壳和grab陷结构上，这表明断层和弯曲过程涉及影响沉积环境的漫长而强烈的构造过程。南北卡罗琳岭之间的沉积层和断层分布不同，这主要归因于不同的裂谷过程。此外，我们提出N65°W走向的古代断裂足以降低进入的卡罗琳岭的屈服强度，以利于与弯曲有关的断裂。在俯冲过程中，即将到来的北卡罗琳岭裂谷很大，而索罗槽的地壳很薄，可以抵抗较小的弯曲弯曲，并产生较大的晃动和抓握结构。传入海洋高原的古代断层和裂谷模型在与弯曲有关的断层中起着重要作用
