Surface wave tomography of the western United States from ambient seismic noise: Rayleigh wave group velocity maps
[1] We have applied ambient noise surface wave tomography to data that have emerged continuously from the EarthScope USArray Transportable Array (TA) between October 2004 and January 2007. Estimated Green’s functions result by cross-correlating noise records between every station-pair in the network. The 340 stations yield a total of more than 55,000 interstation paths. Within the 5to 50-s peri...
متن کاملSensitivity of Near-Surface Shear-Wave Velocity Determination from Rayleigh and Love Waves
Rayleigh and Love waves recorded on seismic-shot gathers can be used to determine the thickness and shear-wave velocity of shallow subsurface layers. After the data are transformed into the k-f domain, the dispersion curve for each of the phases can be picked from maxima on the contour plot. This dispersion curve is then inverted for the velocities and depths. Different frequencies in the dispe...
متن کاملtwo dimensional rayleigh wave group velocity tomography in northwestern part of iranian plateau
summarythe explanation of the elastic, or velocity structure of the earth has long been a goal of the world’s seismologists. for the first few decades of seismological research, the investigation on velocity structure was restricted to the determination of one-dimensional models of the solid earth and of various regions within it. seismologists are currently obtaining three dimensional velocity...
متن کاملSurface Wave Dispersion Measurements and Tomography from Ambient Seismic Noise Correlation in China
We perform ambient noise tomography of China using the data from the China National Seismic Network and surrounding global and PASSCAL stations. The results so far are summarized below. (1) Dispersion measurements and tomography. For most of the station pairs, we retrieve good Rayleigh waveforms from ambient noise correlations using 18-months of continuous data at all distance ranges across the...
متن کاملSurface Wave Tomography of China from Ambient Seismic Noise Correlation
We perform ambient noise tomography of China using the data from the China National Seismic Network and surrounding global and regional stations. For most of the station pairs, we retrieve good Rayleigh waveforms from ambient noise correlations using 18-months of continuous data at all distance ranges across the entire region (over 5000 km) and for periods from 70 s down to about 8 s. We obtain...
