Dynamics of Seismic Sourcesen a circular crack model and its radiation; this is the model most seismologists use to invert source parameters. Finally, we review some recent propositions to explain earthquake complexity and multiple events. Seismic moments, stress drops and corner frequencies may be strongly affected by source complexity.作者: expdient 時(shí)間: 2025-3-22 12:18
The Effect of Green’s Functions on the Determination of Source Mechanisms by the Linear Inversion ofment tensor with the deviatoric component as much as a factor of twenty-five smaller. The time function of the source appears to have a double peaked nature. The fit of the calculated seismograms to the observed is not greatly affected by the assumed Green’s function.作者: Conducive 時(shí)間: 2025-3-22 12:54

In 1961–1962 it was demonstrated that unless stations can be established within 500 kms of a seismic source the best distance for detecting SP P waves is the range 3000 to 10,000 kms.
