WebSeismic Wave Propagation in Stratified Media presents a systematic treatment of the interaction of seismic waves with Earth structure. WebCAT Scans & Seismic Tomography For lack of a perfect analogy, seismic tomography is often compared to a CT scan (aka “Cat scan” for Computed Axial Tomography). The CT scan uses computers to generate a three-dimensional image from a lot of flat X-ray pictures. The basic idea of a CT scan is this: The X-ray
