Research Abstract

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.
