The first partial images of LLSVPs were obtained using this technique, which is greatly complicated by the presence of triplications.
The first partial images of LLSVPs were obtained using this technique, which is greatly complicated by the presence of triplications. This technique consists of solving an inverse problem based on a sequence of iterated prestack depth migrations. A common form of this technique finds perturbations to a 1D structure model such as PREM through inversion of fluctuations in travel times. This technique can also incorporate comparison of direct phases, such as SKS, and reflected phases, such as ScS, in an analysis of differences in arrival times that provides information on structure in the deep mantle. For 10 points, subducted tectonic plates sinking through the mantle can be tracked using what technique that utilizes waves generated by explosions and earthquakes to generate 3D images of the Earth's interior?
