Abstract : This paper discusses the crustal thickness of China deduced from the difference in the arrival time of the S wave and of the reflected and transformed SP' wave as measured at various seismological stations in Wuhan, China. An SP' wave is defined here as an S wave that is reflected upon arrival at the earth's surface, and transformed as a P wave, and reflected again toward the earth's surface by the Mohorovicic-discontinuity. By using suitable crustal parameters in the analysis, it is shown that of the various waves reflected and transformed from an incident S wave, the SP' wave contains the greatest energy. Other waves which are similar to the SP' waves are also discussed. (Author)
