We dedicate this paper to Dimitri Komatitsch and his loving family members, he is a light that has gone out much too early. We also thank Ron Bruhn for his valuable advice about the geological explanation of our eld results. The research reported in this publication was supported by the King Abdullah University of Science and Technology (KAUST) in Thuwal, Saudi Arabia. We are grateful to the sponsors of the Center for Subsurface Imaging and Modeling Consortium for their nancial support. For computer time, this research used the resources of the Supercomputing Laboratory at KAUST and the IT Research Computing Group. We thank them for providing the computational resources required for carrying out this work.
