Abstract
Seismic surveys are based on analysis of complex short wavelength signaIs, while the resolved model elements are often simple and of much longer wavelength. Furthermore, attribute analysis of three component seismic records testifies towarels medium complexities not commonly incorporated in the structural modeIs. To provide better understanding of high frequency wave propagation within the heterogeneous crust, we use finite difference (FD) modeling in 2D and 3D in combination with more conventional analysis of seismological data.
