| Summary: | 碩士 === 國立成功大學 === 地球科學系碩博士班 === 93 === High-resolution shallow seismics and ground penetrating radar (GPR) is employed to investigate the shallow geology of the Tainan Plateau in southwestern Taiwan. The obtained geophysical profiles show that the shallow layers (within 200m depth) are roughly concurrent to the topography. There is a syncline with crest nearly at the peak of the plateau, although faults are interpreted on both the east and west flanks of the plateau. This implies that the structure of Tainan Plateau is mainly a north-south striking syncline. This implies that the dissipation of the plate collision stress in this region (about 1 cm/yr) is mainly by creeping that causes folding, rather than by faulting that causes strong earthquakes. Therefore the Tainan Plateau, being a fault zone, has lower earthquake hazard comparing to the other fault zones in Taiwan.
