Seismic Distance-Amplitude Relations for Short Period P, Pdiff', PP and Compressional Core Phases for delta less than 90 degrees
Abstract
Measurements of log(A/T) reported by the International Seismic Centre, the Vela Observatories, and the Long-Range Seismic Measurements Program are used to define an amplitude-distance curve for the maximum amplitude in the first few seconds of motion for the distance range delta > 90 degrees. In general terms, the corresponding phases are P, P(diff), and PKIKP. Some information is also obtained, however, for the phases PP and PKP2.
