摘要:	研究期間：10108~10207;In southwestern Taiwan, due to the oblique collision of the Eurasian continent, the Manila subduction system presents a very complex seismotectonic features. Located in the offshore Taiwan, a temporary OBS recording network is the best tool to study the seismogenic factor in this area. Not only the earthquake mechanisms play an important role, many studies have also further pointed out that the distribution of geological structures have much inference on the generation of tsunami and produced disaster. Offshore southwestern Taiwan, the analysis of seismic reflection profiles shows the presence of the thrust faults in the leading edge of the Manila Trench. This kind of high angle thrust fault might induce larger surface movement and produce higher tsunami wave. However, the magnitude of earthquakes generated by such thrust faults is usually small; it must depend on a temporary OBS seismic network for the earthquake observation. In this project, we plan to analyze the data recorded by a passive OBS networks located close to the Kaoping canyon and Manila subduction zone. We except to characterize the seismicity in these specific areas in order to better understand the role of Manila subduction zone in the formation of Taiwan and its evolution through time and its relationship with the generation of earthquakes. On the other hand, we will use the micro-seismicity distribution patterns to study the geological structures. This geological map will give a good constrain for tsunami simulation.
