Part-time work image

Recent work in southern Africa has focused on developing a teleseismic travel time tomography image for the upper mantle (James et al. 2001 James Fouch 2002). The objective of teleseismic travel time tomography is to determine a 3D seismic image for a volume of Earth beneath the seismie array based on the arrival times from a large number of source-receiver combinations. The 3D model is normally expressed in terms of perturbations to a reference model in which the velocity is a function only of radius, where the 3D perturbations account for that part of the travel time not explained by the reference model. [Pg.57]
