Outline of Final Research Achievements

This project focused on the segmentation and fault interaction as well rupture mechanisms of the active faults in the eastern margin of the Tibetan Plateau inclunding the Longmen Shan Thrust Belt active fault zone that triggered the 2008 Mw 7.9 Wenchuan earthquake and the Xianshuihe fault zone that triggered the Mw 6.9 Yushu earthquake. During the study of this project, we have published 28 high impact papers in the international journals. As related topics with this project, we have also studied the active faults and paleoearthquakes in Japan, including the Fujigawa-kakou fault zone as a plate boundary and the structural features of fault damage zones and fault rocks developed in the Arima-Takatsuki Tectonic Line and Itoigawa-Shizuoka Tectonic Line active fault systems.
