Abstract
Analytical results are presented which describe ground motions generated by sudden changes in the rate of advance of a curved front of a region of sliding in an inclined fault plane. The elastic-wave emission is computed on the basis of two-dimensional canonical problems for slip-displacement distributions near the rupture front, that are consistent with Mode II and Mode III crack propagation models. Ray theory considerations provide modifications to the two-dimensional radiated fields to account for curvature of the front. In the near-field the ground motion is computed by considering the reflection of rays of body-wave motion at the earth's surface. Surface-wave motions are computed in the farfield.
