About Taiwan

---

     I worked with Prof. Yue-Gau Chen and other friends at National Taiwan University (NTU) since 2001. Our major study is the active structures in landarea of Taiwan, especially the Northern and Eastern Taiwan.

    From 2001 to 2003, I worked on the active tectonics in the Taoyuan-Hukou tablelands, northern Taiwan. The surface deformation features in this area are controlled by two active anticlines and one right-lateral fault system. From the previous publication and my study, we believe those structures are resulted from the inversed old-normal fault system in this area.

    After 2004, We further work on the age and red soil distribution on these tablelands. Our result suggests most of the surfaces were formed around 80-65ka in this area, and the distributions of red soil (lateritic soil) are not only controled by the surface's age, but also controled by the groundwater level and the geomorpholoy in local scale. These results suggest two different things; first, the long-term anticlinal uplift rate is ~ several mm/yr in the Taoyuan-Hukou tablelands and became slower recently. Also, it suggested the lateritic soil is not a good single indicator to the age of the surface at Taiwan.

In 2008, I also worked with Prof Yih-Min Wu and my friend Yuang-Yin Lai about the tectonic indication of Ilan earthquake (ML 5.9) in 2005. The surface displacements associated with the Ilan earthquake suggests it may relate to a dyke intrusion event. This study gives us a better understanding about how the westward propagation of the Okinawa Trough affect to the tectonic framework in the northeast Taiwan.
