This paper summarises the results on active fault studies obtained mainly by the author’s work during the last 10 years. The 1999 Chichi earthquake makes a turning point for active faults study. Many international and interdisciplinary works have been carried out for active faults studies, in which the author has participated in the field of geomorphological study of active fault. Her main contribution is a discussion on the close relationship between the 1999 surface trace and preexisting active fault, estimation of tilt rate and relation between the main fault and subsidiary fault, the possible segmentation based on trenching data (Chelungpu Fault), finding some new active faults and discussion of their implication for the geomorphic evolution, as well as seismotectonic significance (Tunglo Fault System and Touhuanping Fault, northwest Taiwan). Ongoing works on the reverse faults in southwestern Taiwan, are briefly summarized, including significant effect of rapid denudation, that may cause underestimation of length of active faults.
