Many thrust faults are created in the fold-and-thrust belt in the Western Foothills, and the plate-boundary fault of the longitudinal Valley Fault in the eastern Taiwan. These two areas are the most active tectonic areas within the Taiwan orogen, and most of its faults go through metropolis. Besides, the Geology Act passed in 2010 is constructed for the division of the geologically sensitive areas. The purposes of this project are to: (1) investigate the fault activities, to obtain its fault parameter–the long term vertical deformation rate, the long term slip rate and the recurrence interval (time period). (2) investigate and accurately identify the active fault trace. The faults which are investigated for its activities are: the Hsinhua Fault, Sanyi Fault, Milun Fault, Chishan Fault, Meishan Fault, Lichi Fault, and Tuntzuchiao Fault. The faults which are investigated for fault trace are: the Hsincheng Fault, Hsinhua Fault, Hsinchu Fault, Milun Fault, Tachia Fault, the northern segment of Sanchiao Fault, Lichi Fault, and Hengchun Fault. Currently, this year we focus the investigation of the Hengchun, Lichi Fault, and Tuntzuchiao, or Tachienshan Faults.都會區地震災害敏感區長期滑移速率再現週期metropolisseismic hazards zoneslong-term slip raterecurrence interval重要活動斷層帶構造特性調查研究計畫-斷層活動特性分析與評估(4/4)
