SEISMIC VELOCITY, RADIAL ANISOTROPY IN THE CRUST AND UPPER MANTLE OF NORTHEASTERN TIBETAN PLATEAU FROM SURFACE WAVE TOMOGRAPHY
… mantle structure in the NE Tibetan Plateau using surface wave tomography from teleseismic data recorded at the 36 seismic stations of NorthEast Tibet Seismic (NETS) array. The first part of this dissertation is to construct a 3-D SV velocity (VSV) model using Rayleigh wave data in the NE Tibetan …

Seismic Velocity and Radial Anisotropy in the Crust and Upper Mantle of the South Central United States from Surface Wave Tomography
… through the last Wilson cycle. Rayleigh and Love wave phase velocities at the periods of 6-167 s were obtained from ambient noise and earthquake data recorded at 207 broadband stations of the USArray Transportable Array. 3-D shear-wave velocity and radial anisotropy models were derived from the …

Structure and evolution of the Australian continent : insights from seismic and mechanical heterogeneity and anisotropy
… insights from isotropic and anisotropic seismic surface-wave tomography with an analysis of the anisotropy in the mechanical properties of the lithosphere, inferred from the coherence between gravity anomalies and topography. With a new high-resolution waveform tomographic model of Australia, I …

Surface Wave Propagation and Global Crustal Tomography
… calculate Born sensitivity kernels for Rayleigh-wave phase and amplitude measurements that are valid in regions near seismic stations. Calculations of sensitivity kernels for inter-station measurements show that exact travelling-wave representation of Green tensor is necessary when station …

Imaging the crust and uppermost mantle of north central Alaska using the joint inversion of ambient seismic noise correlation and receiver function
… AK to Prudhoe Bay, AK. The source for the surface wave tomography is ambient seismic noise correlation, which correlates the background noise from a seismic station’s continuous record with the noise from another station's record. This returns an empirical surface wave Green function …

Ambient noise tomography for wavespeed and anisotropy in the crust of southwestern China
… Tibetan Plateau and adjacent regions using surface wave tomography. Green's functions for Rayleigh and Love waves are extracted from ambient noise interferometry. Using the Green's functions, we first conduct traditional traveltime tomography for the two shear wavespeeds Vsv and Vsh Their …

Seismic investigations of the northern Transantarctic Mountains
… this dissertation integrates Rayleigh wave surface wave tomography, downward continuation and wavefield decomposition, and seismic anisotropy studies to better characterize the structure beneath the northern TAMs and to assess uplift. Surface wave tomographic images indicate a …

Surface Wave Derived Shear Velocity Structure of the Gamburtsev Subglacial Mountains, Transantarctic Mountains, and West Antarctica and Shallow Seismicity of the Mariana and Tonga Subduction Zones
… specific regions of interest using teleseismic surface waves. We focus our efforts on the Gamburtsev Subglacial Mountains in Chapter 4. This mountain range is located in the center of the East Antarctic Ice Sheet and their origin is enigmatic. Through high-resolution surface wave tomography …

Seismic study of the crust and upper mantle structure in eastern Asia using ambient noise correlation and earthquake data
… upper mantle. Among all these methods, seismic tomography is one of the most powerful tools to image the earth’s structure. Recent theoretical and experimental studies suggest that the media impulse response (Green’s function) of surface wave between two seismic stations can be retrieved from …
