为了了解大洋内弧的形成过程,我们利用伊豆弧北部已有的地震资料进行了地幔楔形成像的地震层析成像。地幔成像结果表明,在观察到厚岛弧壳的地区下方存在低速地幔楔体。除了地幔成像,我们还进行了OBS实验,在伊豆-博宁弧南获得了新的地震数据。
英文摘要
In order to understand formation processed of an intra-oceanic arc, we performed seismic tomography for mantle wedge imaging by using existing earthquake data in the northern Izu arc. Results of mantle imaging shows that there are low velocity mantle wedge beneath areas where thick island arc crust is observed. In addition to the mantle imaging, we carried out OBS experiment to obtain new earthquake data in the southern Izu-Bonin arc.
