Andreas Fichtner on the Frontiers of Seismic Imaging
In previous episodes of Geology Bites, Barbara Romanowicz gave an introduction to seismic tomography and Ana Fereira talked about using seismic anisotropy to reveal flows within the mantle. In this episode, Andreas Fichtner explains how, despite the many fiendish obstacles that stand in our way, we are making steady improvements in our ability to image the Earth on both regional and global scales. These give us confidence that we can make three-dimensional maps of certain structures, such as the plume below Iceland, cold continental interiors, mid-ocean ridges, and the large low shear-velocity provinces.
Fichtner is a Professor in the Department of Earth and Planetary Sciences at the Federal Institute of Technology in Zurich.
