|Other Titles:||Distribution and Geomorphic Characteristics of Active Fault in Central Taiwan|
Department of Geography, NTNU
Using aerial photograph interpretation and field investigation, the active faults are recognized in central Taiwan. They distributed in western foothill between Ta-tu river and Cho-shui river and late Pleistocene tablelands including Ho-li, Ta-tu, Pa-kua and Hsin-she. The faults are striking north to south mainly and thrusting over from east to west. The morphology of active fault such as fault scarp, flexural scarp, range-facing scarp are significant. Most of faults have I and II in certainty level. The amount of deformtion on old terraces are larger than that of the new ones. It shows the accumulation of faulting since Pleistocene. Under the effect of Che-lung-pu fault, the Tai-chung basin have subsided and asymmetrical anticline occurred on the Ta-tu and Pa-kua tablelands which produced the channel diversion in the lower drainage system, such as Ta-chia River diverted to Wu River. According to the faults truncating through lower terraces and flooding plain in Chi-chi earthquake, the faults along the foothill of central Taiwan are still active up to recent time.
