S-wave velocity structure in the SE Tibetan plateauElsevier BV - Tập 29 - Trang 165-172 - 2016
Yan Cai, Jianping Wu, Weilai Wang, Lihua Fang, Liping Fan
We use observations recorded by 23 permanent and 99 temporary stations in the SE Tibetan plateau to obtain the S-wave velocity structure along two profiles by applying joint inversion with receiver functions and surface waves. The two profiles cross West Yunnan block (WYB), the Central Yunnan sub-block (CYB), South China block (SCB), and Nanpanjiang basin (NPB). The profile at ~25°N shows that the...... hiện toàn bộ
Heterogeneous strain regime in the eastern margin of Tibetan Plateau and its tectonic implicationsElsevier BV - Tập 28 - Trang 1-10 - 2015

The eastern margin of Tibetan Plateau is one of the most active zones of tectonic deformation and seismicity in China. To monitor strain buildup and benefit seismic risk assessment, we constructed 14 survey-mode global position system (GPS) stations throughout the northwest of Longmenshan fault. A new GPS field over 1999–2011 is derived from measurements of the newly built and pre-existing station...... hiện toàn bộ
Depth determination of the Moho interface beneath the Tibetan plateau and other areas of ChinaElsevier BV - Tập 25 - Trang 415-431 - 2012
Youshun Sun, Diming Yu, M. Nafi Toksöz, F. Dale Morgan, Xiyu Wang, Jinrong Su, Jun Liu
We apply the adaptive moving window method of Sun et al. to the most recent catalog data and the data recorded by portable stations to construct the velocity structure of the crust and upper mantle, and to determine the depth of the Moho interface beneath the Tibetan plateau and other areas of China. We first select 2 600 locations in the study region with 1° intervals, then at each location inver...... hiện toàn bộ
A note on the equivalence of three major propagator algorithms for computational stability and efficiencyElsevier BV - Tập 25 - Trang 55-64 - 2012
Yanlu Ma, Rongjiang Wang, Huilan Zhou
It is shown in this note that the three methods, the orthonormalization method, the minor matrix method and the recursive reflection-transmission matrix method are closely related and solve the numerical instability in the original Thomson-Haskell propagator matrix method equally well. Another stable and efficient method based on the orthonormalization and the Langer block-diagonal decomposition i...... hiện toàn bộ
