The Interpretation of Moment Tensor Inversionsis ideally suited for use in the forward problem of generating synthetic seismograms for most sorts of natural and artificial sources. Furthermore, this straightforward approach for the computation of synthetic seismograms would indicate a relatively simple inverse problem. However, it is the very g

Some Recent Extensions of the Reflectivity Methodorm of the reflectivity method, the combination with generalized ray theory is described which allows calculations of many interesting seismic phases, such as surface reflections and surface multiples, for only little additional computing time. Then the calculation of complete seismograms is describ

High Frequency Toroidal Modesroach. The information content of the set of high frequency modes is assessed, and a simple procedure developed to compute the perturbations produced by the Moho. Finally Brune’s method of extracting toroidal mode data from body wave pulses is discussed, and in particular the systematic error introd

Within each region, at each frequency and slowness, the wave functions are constructed from a Langer uniform approximation in terms of Airy functions supplemented by an expansion in the elastic parameter gradients which
