Abstract

The study of the propagation of seismic waves through a medium having attenuation factors varying as the first power of the frequency has been extended to the geometry used by Lamb for the perfectly elastic case. The results show three pulse groups corresponding to P, S, and R events. For high Q, all three pulses are very sharp; these pulses broaden at rates proportional to the product of the distance and 1/Q. For symmetric pulse input and high Q, the R pulse is noticeably asymmetric, the P pulse only weakly so.
