Joint Inversion of Receiver Functions and Surface-wave Dispersion
Teleseismic P-wave receiver functions and surface-wave dispersion measurements can be employed to simultaneously infer the shear-wave velocity distribution with depth in the lithosphere. Receiver functions are primarily sensitive to shear-wave velocity contrasts and vertical travel times and surface-wave dispersion measurements are sensitive to vertical shear-wave velocity averages, so that the...
متن کاملcrustal velocity structure of kerman region from joint inversion of receiver functions and rayleigh waves group velocity dispersion
iran is situated in one of the world's seismic regions and the possibility of destructive earthquakes in most regions of the country has given great significance to recognition of iranian seismic nature from a seismic and seismotectonic standpoint. study of the crust and upper mantle velocity structure in the iranian plateau provides better understanding of its evolution and tectonic histo...
متن کاملApplication of Joint Receiver-function Surface-wave Dispersion for Local Structure in Eurasia
Subsurface geology generally has a broad wave number spectrum containing sharp, or high wave-number, changes in velocity near major geologic boundaries and smooth low wave-number variations in regions of relatively uniform geologic structure. Access to the full spectrum of earth structure requires that we exploit signals that span a wide frequency range and that are sensitive to the entire spec...
متن کاملShear wave tomography of China using joint inversion of body and surface wave constraints
[1] The India-Eurasia collision and the decratonization of the North China Craton have drawn much attention from the scientific community. Here we provide the first large-scale S wave velocity model for China (CH11-S) based on constraints from both teleseismic surface and body waves. We take advantage of the recent deployment of the 140 permanent stations of the Chinese Digital Seismic Network ...
متن کاملCrustal and Upper Mantle Structure from Joint Inversion of Body Wave and Gravity Data
We present a preliminary model of the three-dimensional seismic structure of the Iran region obtained via simultaneous, joint inversion of body wave travel time and gravity observations. The body wave data set is derived from location calibration efforts and includes a large (>1000 events) subset of GT5-level events. The arrival time data sets for these events include many readings of direct cr...
