We present a new numerical modelling approach for frequency-domain finite-difference (FDFD) wave simulations. The new approach is developed as an extension to standard FDFD modelling schemes, when wave propagation simulations ...
An adaptive wavelet-based finite-difference method for 2-D SH -wave propagation modelling is presented. The discrete orthogonal wavelet transform allows the decomposition of spatial wavefield coordinates on to different ...
An investigation of the teleseismic P-wave coda is performed using the single-scattering approximation. The method allows one to image short-wavelength scale (<=2 km) velocity and density heterogeneities and structures ...
