Abstract
The application of iterative imaging techniques has enabled a detailed mapping of the P-wave velocity heterogeneity in large parts of the Upper Mantle beneath Central Europe, the Mediterranean and the Middle East (Spakman, 1985). More than half a million ISC P delay times are simultanuously inverted for estimates of seismic wave velocity anomalies, earthquake relocation parameters and near station velocity anomalies. In principle the employed tomographic method is based on a division of the Upper Mantle area in a large number of cells and a linearization of the travel time integral with respect to a reference velocity model.
