Phenomenological description of seismic sources in a pre-stressed, self-gravitating, thermo-visco-elastic earth model

M. BONAFEDE, E. BOSCHI

Abstract


SUMMARY - The equations of motion for a pre-stressed, self-gravitating,
thermo-viscolastic Earth model undergoing a dislocation are solved through a
normal mode expansion of the displacement field. The non-hermiticity of the
involved convolution operator is shown not to allow the stress relaxation to be
included in the model stress. Accordingly, the stress glut moment tensor cannot
be assumed to be strictly localized within the seismic source region.
