Summary Theoretical expressions are derived for the displacement, velocity and stress in the time domain induced by an axially symmetric shearing stress applied at the inner surface of a spherical cavity in a hornogeneous, isotropic, elastic medium of infinite extent. Theoretical seismograms are computed for a step source and for three sources with exponential decay in time. A satisfactory time-dependence of the source can be obtained by combining the step source with one or more exponentially decaying sources. 相似文献

Preseismic lithospheric deformation at a subduction zone can be modelled as dip-slip dislocation on an inclined fault or as
flexure of a thin plate. Both these models predict a region of positive topography known as forebulge or outer rise. By matching
the location and the magnitude of the forebulge, we derive useful relations between the dip-slip fault parameters and the
plate parameters. In particular, we determine the width of a long dip-slip fault of given dip corresponding to a semi-infinite
plate of given thickness. The displacement profiles of the two models are also compared. 相似文献

In order to consider the effect of anisotropy on the periods of the oscillations of the Earth, the problem of toroidal oscillations
of a transradially isotropic elastic sphere is considered. At each point, the medium is assumed to be transversely isotropic
about the radius through the point. The roots of the frequency equation are obtained for different values of the anisotropy
parameter α. It is found that, for large order oscillations, the percentage change in the frequency of the toroidal oscillations
on account of the anisotropy is nearly equal to |α-1| × 100. 相似文献
