南沖繩海槽濁流沈積物之分布與可能傳輸途徑(1/2)

In the past four years, our research in the southernmost part of Okinawa Trough suggest that
the turbidite layers in deep sea sediments may caused by those large earthquakes (ML＞6.8)
occurred off eastern Taiwan. These turbidite layers give us an excellent chance to discuss the
relationships between modern earthquake observation records and stratigraphic records.
In this project, we expect to combine the geochronological data, particle analysis results and
X-radiograph images to help us understand the source and transport of the turbidites. It also can
give us some basic information about how and where can earthquake induce slope failure and the
scope of influence in the future. Finally, we hope this study can help us make a rational
assessment of the difficulties by using turbidite records as an important tool for paleo-seismic
research, and the scheme for solving the problems.
