WebSeismic tomography is an imaging technique that uses seismic waves generated by earthquakes and explosions to create computer-generated, three-dimensional images of Earth's interior. CAT scans are often used as an analogy. Here we simplify things and make an Earth of uniform density with a slow zone that we image as a magma chamber. Webkinds of noise in the data, seismic imaging is conducted to produce various forms of imagery for the interpretation process. The seismic imaging methods include seismic migration, seismic tomography, and many other methods of extracting various seismic attributes. Some people call seismic imaging methods the advanced processing. The …
