Abstract: A comparison of theoretical seismograms under discussion with four teleseismograms recorded by WWSSN of SBA (New Zealand) and SPA (U.S.A.), shows that the crustal thickness beneath South Pole is a double-layered structure, about 45 km; crustal thickness below the Ross Sea Beach, a single structure, is about 24 km; and at the depth of 350 - 450 km there exists a low velocity layer. The above results indicate the different tectonic characteristics on both sides of Antarctic Transantarctic Mountains.
