The paper develops a reliable numerical method to solve inverse dynamic problem for elastic waves equation on the base of nonlinear least-squares formulation which is widely known as Full Waveform Inversion (FWI). The key issue on this way is correct reconstruction of macrovelocity component of the model with input seismic data without time frequencies less than 5-7Hz and reasonable source-recievers offsets. To provide correct macrovelocity reconstruction we introduce modified elastic FWI formulation which is sensitive to smooth space variations of both Vp- and Vs-velocity distributions
