Shock Waves, Free Oscillations, and the Earth's Interior

Abstract

The compressional velocity structure of the earth is used to generate shear velocity and density structures which are consistent with mass, moment, and the periods of free oscillation. The inversion scheme uses variational partial derivatives but iteration is required in order to obtain agreement between a predicted and a calculated model. Three parameters of the resulting models, namely, density, seismic parameter ø and the pressure derivative of the bulk modulus can be directly compared with reduced shock wave data. Such a comparison yields the composition in the various regions of the earth.
