| Outline of Final Research Achievements |
Izu-Bonin-Mariana Arc (IBM) is the intraoceanic arc resulting from a subduction of the Pacific Plate beneath the Philippine Sea Plate. The purpose of this study is to understand the magma plumbing system below Kanto region using receiver function (RF) analysis which is appropriate for high-resolution imaging. The result of RF analysis around Kanto region revealed the spatial distribution of the subducting IBM and the magma chamber of Mt. Fuji with a width of 40 km in horizontal direction and 20 km width in vertical direction.
