文摘
- •
Time- and frequency-domain cross-correlation methods are proposed for basin scale studies.
- •
Rayleigh phase velocity dispersion curves are calculated from 0.1 to 8 Hz.
- •
Seismic ambient noise highly correlates in stations over stiff soil deposits of the Basin.
- •
Shear wave velocity profiles of Santiago gravels have a pronounced increase rate with depth.
- •
The impedance contrast between the Santiago gravels and the underlying bedrock is negligible.
