Abstract:

Measurements of logAT 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, Pdiff, and PKIKP. Some information is also obtained, however, for the phases PP and PKP2.
