The western Taiwan Foreland Basin lies on the eastern part of Taiwan Strait. Structures in this region are dominated by crustal stretching and a series of flexural normal faults have been developed since Late Miocene owing to the flexural of the Eurasia Plate. Through deciphering multi-channel seismic data, these flexural features are analyzed in the offshore Changhua coastal area. The flexure normal faults are important features to realize structural activities in the western Taiwan Foreland Basin. It should be a significant issue to decipher whether these faults are still active.
In this study, we analyze all the available seismic reflections profiles in the central part of the Taiwan Strait, and have observed many pre-Pliocene normal faults that are mainly distributed in the middle of the Taiwan Strait to Changyun Rise. We tentatively suggest that the formation of these faults may be associated with the formation of the foreland basal unconformity. So, we idenify the faults from multi-channel seismic profiles, and try to recognize their continuity.
For getting the dip angles of the faults, we convert the seismic profiles from time domain into depth domain. We can provide important parameters to sandbox experiment to evaluate the seafloor stability of this area. As our government plans to establish offshore wind power generaters in this area, I hope this research could contribute to that green energy project.
