Imaging complex regions or difficult terrains like the sub-volcanic sediments or thrust fold belt areas is crucial to understanding the earth's subsurface. Active Seismic Tomography: Theory and Applications describes current technologies for the study of seismic velocities and the elucidation of fine details of the subsurface. Key use cases include hydrocarbon reservoir characterization, identification of faults and channels, and stratigraphic and structural traps.

This volume is a valuable resource for academics and professionals interested in using or developing integrated imaging approaches of the Earth's subsurface.
