Body Force Equivalents for Stress-Drop Seismic Sources.

摘要

The equivalent body forces for a stress-drop seismic source are found. When the isotropic stress drop and one of the three principal stress drops are zero, then the equivalent body forces are the same double couple without moment which would result from a shear dislocation. In general, however, all six stress-drop components must be specified as independent functions of time. (Author)
