Abstract
The formulation derived in Part I of this paper, to obtain disturbances at a surface of a medium with superficial multi-layers due to a dimensional fault is revised by taking surface wave contributions approximately into consideration.
Surface accelerations due to a simple source model with source time function of ramp type are found to be too small, even if our interest in the present study is on rather long-period components. One possibility is shown that rather large accelerations are obtained by adopting different source time functions from the simple ramp type, keeping other focal factors the same as in the presently available fault model.
Accelerations thus obtained are of course only tentative and their absolute values cannot be discussed at the present stage of seismology. However, if surface structures at many places are clarified and detailed behaviors of short-period components in the source time function, especially for large earthquakes, are elucidated, then the present formulation may make it possible to discuss even absolute values of accelerations.
