Structure of the subduction zone south of Taiwan constrained by OBS data / 利用海底地震儀資料研究南台灣隱沒構造

碩士 / 國立臺灣大學 / 地質科學研究所 / 101 / Along the Manila trench the oceanic part of the Eurasian plate, i.e., the South China Sea (SCS) basin,is subducting eastward under the Philippine Sea plate. The Manila trench terminates in the north offshore southern Taiwan, where the subduction is impeded by the collision between the Luzon arc and the Eurasian continental margin which have built the Taiwan orogeny. The subduction zone structure at the ocean-continent junction south of Taiwan is so far unknown because of the lack of in-situ sampling. We have conducted OBS experiments in this region during 2009-2011, and conbined it with CWBSN as onshore-offshore network. Events with M > 2 were relocated to better delineate the crustal and slab structure. We carried out inversion for Vp. In relocation and 1D model inversion, we used height correction which can put station into any layer of velocity model to converge in 1D model inversion.
