High-resolution surface-wave tomography from ambient seismic noise.
Cross-correlation of 1 month of ambient seismic noise recorded at USArray stations in California yields hundreds of short-period surface-wave group-speed measurements on interstation paths. We used these measurements to construct tomographic images of the principal geological units of California, with low-speed anomalies corresponding to the main sedimentary basins and high-speed anomalies corr...
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...

12 [1] We perform ambient noise tomography of China using data from the China National Seismic Network 13 and surrounding global and regional stations. For most of the station pairs, we retrieve good Rayleigh 14 waveforms from ambient noise correlations using 18 months of continuous data at all distance ranges 15 across the entire region (over 5000 km) and for periods from 70 s down to about 8 ...
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 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...
