An east–west trending, high-density seismic array was deployed along the eastern margin of Tibetan Plateau to investigate its eastward expansion. The 160 km long spans Ruoergai basin, Minjiang fault, Minshan Mountains, Tazang and West Qinling. included 330 short-period seismographs spaced at 500 m intervals, which recorded teleseismic 3-component waveforms over a one month period. P-wave receiver functions calculated from 35 events provided an image crustal structure. results show massive...
The convergence between the Indian and Eurasian plates has produced thick crust uplifted Tibetan plateau since about 50 Ma. However, deformation of mantle lithosphere is still a puzzle. geometry subducting beneath thickening or/and delamination are keys for understanding continental collision process evolution plateau. knowledge been restricted due to sparse data coverage in Tibet. In this study, S-wave receiver functions calculated using tele-seismic waveforms recorded by two broadband...
In order to improve the fine structure inversion ability of igneous rocks for exploration underlying strata, based on particle swarm optimization (PSO), we have developed a method seismic wave impedance inversion. Through numerical simulation, tested effects different algorithm parameters and model parameterization methods PSO inversion, analyzed characteristics method. Under conclusions drawn from propose scheme combining cross-moving strategy divided block high-frequency filtering...
Abstract Remarkable V‐shaped conjugate strike‐slip faults extend along the Bangong–Nujiang suture in central Tibet. Motions of these are considered to accommodate ongoing east–west extension and north–south contraction. Fabrics within fault zone that anisotropic seismic waves can provide clues as unusual scale style lithospheric deformation. With goal determining upper‐crustal anisotropy pattern Tibet, we measured shear‐wave splitting parameters (fast wave polarization direction delay time)...

Seismic ray tracing in anisotropic media with irregular surface is crucial for the exploration of fine crustal structure. Elliptically medium type only four independent elastic parameters. Usually, this can be described by vertical phase velocity and horizontal seismic wave propagation. Model parameterization study flexible triangular grids, which beneficial description high degree approximation. Both velocities are defined respectively, used distribution everywhere model linear...
Abstract Detection of hidden faults and sedimentary layers in the urban subsoil is significant for utilization underground space, earthquake hazard mitigation, so forth. Guilin, located southwest China, well known development most typical karst landform world has become an international tourist city that needs scientific planning knowledge space. After collecting waveform data recorded continuously over a period about 1.5 months by dense array 114 short-period seismic stations installed...
In order to improve the measurement accuracy of intelligent water meter, a high precision ultrasonic flowmeter is designed. The device integrates functions CPU, DSP and FPGA on one chip complete timing function, which effectively improves integration stability system. system uses time difference method measure liquid velocity, Slices Xilinx Corporation smoothing filter function. has good application prospect.
