Part of the Shear Zone channel. A quick introduction leading to seismic tomographic as the fundamental tool for imaging the deep earth, via the Preliminary Reference Earth Model, some basics on travel-time curves and seismic body waves. This material was set as a refresher for students to support content on 3D tectonics and structure.
