Overview
- Employs the partition modeling approach to invert for a 3D model based on a collection of the crisscrossing 2D models that densely transect the region
- Enables imaging 3D anisotropy with high resolution by using the full-wave method and multiscale inversion
- Discusses the constraints both on mantle flow for geodynamics and on crustal deformation for tectonics using imaging 3D anisotropy
- Nominated as an outstanding contribution by the Department of Geosciences, National Taiwan University in 2016
- Includes supplementary material: sn.pub/extras

About this book
This book presents investigations on the Earth's seismic structure using both active-source and natural earthquake records. It discusses the ground-truth data obtained from the TAiwan Integrated GEodynamics Research (TAIGER) active-source experiments that provides excellent and unique insights into the shallow crustal structures beneath Taiwan. It also explores the full-wave sensitivity kernels, which account for the effects of all possible wave interferences involved in shear-wave splitting and therefore loosen the restrictions on source-receiver geometry amenable to shear-wave splitting analysis. Moreover, it describes the 3D Fréchet kernels, which enable us to resolve the vertical and lateral variations in seismic anisotropy and obtain 3D images of the Earth's anisotropic structure, as well as the practice in Southern California that enables us to infer the state of the stress and strain in the lithosphere and the dynamics of the asthenospheric mantle flow for a better understanding of the strength and deformation in the upper mantle beneath the San Andreas Fault system.

Description of Research
Yu-Pin Lin is interested in numerical simulations such as the finite-difference method, normal-mode summation, and WKBJ method and also imaging the seismic structures in the Earth's interior. For the isotropy tomography, he used the observed ground-truth first-arrival times to invert for the 3D structures of the shallow crust by a wavelet-based iterative multi-scale tomography inversion. For the anisotropic aspect, he combined their full-wave method based on normal-mode summation with a wavelet-based inversion in a multi-scale anisotropy tomography using teleseismic records. The high-resolution images of azimuthal anisotropy help them better constrain the deformation and dynamics of the lithosphere and upper mantle. He is now focusing on the attenuation tomography. Understanding of the crustal attenuation structures enables themto have a better high frequency ground motion simulations for seismic hazard analysis.
