In this study, we adopt a damping least-square inversion method to investigate Qp and Qs structures of the crust in southwestern Taiwan. Previous studies have shown that the velocity structure can be used as an indicator of the geometry of a fault and the estimate of strong motion. Therefore, the goal of this research is to obtain the seismic attenuation structure and seismic characteristics of this area with respect to wave propagation. The distributions of Qp and Qs and their association with fault activities are also investigated. Our results indicate that variations in the velocity structure of southwestern Taiwan are caused by local geological structures, such as fault crossings. We also find that most earthquakes occur in areas that have greatly varying Qs gradients. In addition, through a simulation of strong earthquakes that have occurred in this area, the obtained 3D velocity structure can be more reliably utilized in seismic hazard assessments. |
