106_Study on the Crustal Deformation in the Southwest Taiwan

Project Details

Description

Southwest Taiwan with a crustal horizontal shortening rate of 4 cm per year, e.g. half of the totalshortening rate of Taiwan orogeny is considered as the most active region in Taiwan Island. Theregion includes two special municipalities, Tainan and Kaohsiung inhabited by nearly 5 million ofcitizens. Unfortunately, doomed to its tectonic setting, there are many active geologic structures withan earthquake-hazard potential. Therefore, it is urgent and critical to characterize these activestructures and explore their resultant mechanisms, which have been debated as either faulting ormud diapiring. In addition, the ground-surface traces for numerous active fault remain ambiguous.In this study, I plan to perform topographic analyses and field investigation to locate the fault tracesand characterize their activity using LiDAR digital topographic data, upcoming UAV aerialphotographs and InSAT measurements. Also, I plan to explore possible mechanisms attributed to thestrain localizations in specific areas. The term for this project is scheduled for at least 3 years.Imperative targets are Chishan fault, Hsiaokangshan fault-Takagshan anticline and Hiuchiafault-Nuishan anticline. The outcome of this study is expected to ease the disputation on themechanism of crustal deformation and contribute the fault zone delineation, and earthquake hazardand risk assessment.
