Abstract:	研究期間：10108~10207;This project is a three-years project and belongs to the second phase of the Taiwan-Philippines Geodynamic project. The tectonics of the region between Taiwan and Luzon islands is complicated and is involving into the formation Taiwan orogen. The South China Sea lithosphere has subducted eastward beneath the Huatung Basin (Philippine Sea Plate) along the Manila trench and has formed the Luzon Arc. The Luzon Arc has formed just before its collision with SE Eurasian margin and has created the Taiwan orogen. Morphologically, the accretionary prism of the Manila subduction zone has widened northward while the Luzon Arc has widened southward. The Luzon Arc has even double zones in the southern portion. It is worthy of noting that the Manila subduction does not accompany the formation of a back-arc basin. Further east, it is bounded by the Gagua Ridge. The tectonics as well as the crustal structures of the southern Manila subduction zone was rarely understood, especially the deep crustal structure related to the seismogenic zone. Under the Earth Science cooperation between Taiwan and the RP and with the new MCS data collected during 2009 Taiger cruise, we would like to study the seismogenic characteristics along the Manila subduction zone. In the first year, we will focus in the area to the north of Batan islands. In the second year, we will study the area between Luzon and Batan islands. In the third year, we will focus in the west of Luzon island and extends to the south near the Midoro island, trying to understand the crustal structures in the seismogenic zone.
