Seismic Tomography

In this animation we simplify things and make an Earth of uniform density (isotropic; constant velocity sphere) with a slow zone that we image as a magma chamber for simplicity. For reference, the Earth figures below show the difference between our simple animation and a body with changes in rock type and temperature that cause the seismic waves to refract and bend when transmitted between different rock compositions.
