Session ID#: 12424

Session Description:
Through seismic imaging we infer the Earth’s dynamics, composition and evolution. Our view of the Earth is transforming with time thanks to the advent of high-density networks, new modeling techniques, and unprecedented HPC capacity. We invite presentations on seismic imaging from regional to global scales with special focus on quantitative inferences of Earth dynamics as well as discussions on the imaging method resolution that could limit our interpretations. We also welcome presentations on novel techniques that harness large emerging data sets, original measurements, and modern computational methods to develop these intriguing images. Topics like the joint inversion of complementary geophysical data sets, forward and inverse modeling of full waveforms, seismic interferometry, and probabilistic approaches will be gladly received. This session is complementary to session "Imaging the Earth I: Theory and methods at reservoir and local scales". Together, they are intended to promote communication between exploration and global seismology.
